Getting Started with LSAT Logical Reasoning: Complete Prep Guide

LSAT Logical Reasoning is the most important section of the LSAT, comprising approximately 50% of your total score with two separate 35-minute sections. Mastering Logical Reasoning requires understanding argument structure, recognizing question types, and developing critical thinking skills that are fundamental to legal reasoning and law school success.

What is LSAT Logical Reasoning?

According to the Law School Admission Council (LSAC), Logical Reasoning questions evaluate your ability to examine, analyze, and critically evaluate arguments as they occur in ordinary language. These questions are based on short arguments drawn from newspapers, magazines, scholarly publications, advertisements, and informal discourse—mirroring the types of reasoning you'll encounter in law school and legal practice.

LSAT Logical Reasoning Section Format

  • Number of Sections: Two scored Logical Reasoning sections per LSAT
  • Time Per Section: 35 minutes
  • Questions Per Section: 24-26 questions
  • Total Questions: Approximately 48-52 Logical Reasoning questions
  • Weight: Approximately 50% of your total LSAT score (most heavily weighted section)
  • Question Format: Short passage (50-100 words) followed by one question (rarely two)
  • Time Per Question: Approximately 1 minute 20 seconds

💡 Key Insight: Logical Reasoning has the highest correlation with first-year law school grades (correlation coefficient of 0.511 according to LSAC research), making it the best predictor of law school success among all LSAT sections.

Why Logical Reasoning Matters for Law School

Arguments are fundamental to law, and analyzing arguments is central to legal analysis. As a law student and future attorney, you will need to:

  • Draw on skills of analyzing, evaluating, constructing, and refuting arguments
  • Identify what information is relevant to an issue or argument
  • Determine what impact further evidence might have on arguments
  • Reconcile opposing positions
  • Use arguments to persuade others

The Logical Reasoning section directly assesses these fundamental legal reasoning skills, which is why law schools weight LSAT scores heavily in admissions decisions.

Understanding Argument Structure

Every LSAT Logical Reasoning question centers on understanding how arguments work. Before diving into specific question types, you must master the fundamental components of arguments.

The Three Core Components of Arguments

📋 1. Premises (Evidence)

Definition: Facts, data, or evidence provided to support a conclusion. Premises are the foundation of the argument.

Key Characteristics:

  • Must be accepted as true on the LSAT (even if they seem false)
  • Provide support for the conclusion
  • Often introduced by premise indicators: because, since, for, given that, as evidenced by, due to

Example Premise:

"Because the company's revenue increased by 20% last quarter..."

This is evidence that supports a claim the author will make.

🎯 2. Conclusion (Claim)

Definition: The main point or claim the author is trying to prove. This is what the author wants you to believe based on the premises.

Key Characteristics:

  • The "so what?" of the argument—why it exists
  • Has evidence supporting it but doesn't support other claims
  • Can be challenged or debated (unlike premises)
  • Often introduced by conclusion indicators: therefore, thus, so, hence, consequently, it follows that, clearly

Example Conclusion:

"...therefore, the company will likely expand its workforce next year."

This is the claim being argued based on the revenue increase premise.

🔗 3. Assumptions (Unstated Connections)

Definition: Unstated premises that must be true for the argument to be valid. Assumptions bridge the gap between evidence and conclusion.

Key Characteristics:

  • Never explicitly stated in the passage
  • Necessary for the conclusion to logically follow from the premises
  • What the author takes for granted
  • The "missing piece" that makes the argument work

Example Assumption:

Premise: The company's revenue increased by 20%

Conclusion: The company will expand its workforce

Assumption: Companies typically hire more employees when revenue increases (not stated but must be true for the argument to work)

The Fundamental Logical Reasoning Formula:

\[ \text{Premises} + \text{Assumption} = \text{Conclusion} \]

This formula is the foundation of most Logical Reasoning questions, especially Assumption, Strengthen, Weaken, and Flaw questions.

Identifying Argument Indicators

Recognizing indicator words helps you quickly identify argument structure:

Indicator TypeCommon Words/PhrasesPurpose
Conclusion Indicatorstherefore, thus, so, hence, consequently, it follows that, clearly, evidently, accordinglySignal that what follows is the main claim
Premise Indicatorsbecause, since, for, given that, as, inasmuch as, due to, for the reason thatSignal that what follows is evidence
Contrast Indicatorshowever, but, although, despite, yet, nevertheless, nonethelessSignal opposing viewpoints or concessions
Evidence Indicatorsstudies show, research indicates, the data reveal, statistics demonstrateIntroduce factual support

Types of Conclusions

Logical Reasoning arguments can contain different types of conclusions:

  • Main Conclusion: The primary claim the entire argument supports. Every argument has one main conclusion.
  • Intermediate Conclusion: A claim that is both supported by premises AND supports the main conclusion. It serves as a stepping stone in the argument.

Example with Intermediate Conclusion:

Premise: Studies show that regular exercise reduces stress hormones.

Intermediate Conclusion: Therefore, regular exercise improves mental health.

Main Conclusion: Consequently, employers should provide gym memberships to employees.

The intermediate conclusion is both supported (by the premise about stress hormones) and provides support (for the main conclusion about employer policy).

The 10 Core Skills Tested in Logical Reasoning

According to LSAC, Logical Reasoning questions assess a wide range of critical thinking skills. Understanding what's being tested helps you approach each question strategically.

1. Recognizing Argument Parts

Identifying premises, conclusions, assumptions, and their relationships within arguments

2. Recognizing Reasoning Patterns

Identifying similarities and differences between different patterns of logical reasoning

3. Drawing Conclusions

Making well-supported inferences based on provided information

4. Reasoning by Analogy

Applying logical structures from one situation to parallel situations

5. Recognizing Disagreements

Identifying misunderstandings or points of disagreement between different positions

6. Evaluating Evidence

Determining how additional evidence affects an argument's strength

7. Detecting Assumptions

Identifying unstated premises that arguments rely upon

8. Applying Principles

Identifying and applying general rules or principles to specific situations

9. Identifying Flaws

Recognizing errors and weaknesses in argumentative reasoning

10. Identifying Explanations

Distinguishing between explanations and arguments, and evaluating explanatory hypotheses

✅ Important Note: You do NOT need to know formal logic terminology like "ad hominem," "syllogism," or "modus ponens" for the LSAT. However, you DO need a university-level understanding of basic concepts like argument, premise, assumption, and conclusion.

Major Logical Reasoning Question Types

Logical Reasoning questions fall into approximately 10-12 major categories. Recognizing the question type immediately tells you what strategy to use and what the correct answer must accomplish.

Category 1: Assumption Questions

🔍 Necessary Assumption Questions

Question Stems:

  • "Which of the following is an assumption required by the argument?"
  • "The argument depends on assuming which of the following?"
  • "The argument relies on which of the following?"

What They Ask: Identify an unstated premise that MUST be true for the conclusion to follow from the evidence.

Strategy:

  1. Identify the conclusion and premises
  2. Find the gap between evidence and conclusion
  3. Pre-phrase what's missing
  4. Use the Negation Test: negate each answer choice—if negating it destroys the argument, it's necessary

Necessary Assumption Formula:

\[ \text{If NOT Assumption} \rightarrow \text{Argument Falls Apart} \]

✅ Sufficient Assumption Questions

Question Stems:

  • "The conclusion follows logically if which of the following is assumed?"
  • "Which of the following, if assumed, enables the conclusion to be properly drawn?"
  • "The conclusion can be properly inferred if which one is assumed?"

What They Ask: Identify a statement that, if added to the argument, would make the conclusion logically certain.

Strategy:

  1. Identify the gap in the argument
  2. Look for an answer that completely bridges the gap
  3. The correct answer will make the argument airtight (100% valid)
  4. Sufficient assumptions are often stronger/broader than necessary

Category 2: Strengthen/Weaken Questions

💪 Strengthen Questions

Question Stems:

  • "Which of the following, if true, most strengthens the argument?"
  • "Which one of the following, if true, provides the most support for the conclusion?"

What They Ask: Which answer choice makes the conclusion more likely to be true (doesn't have to prove it).

Strategy:

  1. Identify the conclusion and evidence
  2. Determine the assumption
  3. Look for answers that confirm/support the assumption
  4. Don't require proof—just make the argument stronger
  5. Never question the truth of stated premises

⚠️ Weaken Questions

Question Stems:

  • "Which of the following, if true, most weakens the argument?"
  • "Which one of the following, if true, casts the most doubt on the conclusion?"

What They Ask: Which answer choice makes the conclusion less likely to be true.

Strategy:

  1. Identify the conclusion and evidence
  2. Determine the assumption
  3. Look for answers that attack/undermine the assumption
  4. Don't require disproof—just make the argument weaker
  5. Never attack the premises (accept them as true)

Category 3: Flaw Questions

❌ Flaw/Logical Vulnerability Questions

Question Stems:

  • "The reasoning in the argument is flawed in that it..."
  • "The argument is vulnerable to criticism on the grounds that it..."
  • "Which of the following describes an error in the argument's reasoning?"

What They Ask: Identify the logical error in the argument's reasoning.

Common Flaws:

  • Confusing Correlation and Causation: Assumes that because two things happen together, one causes the other
  • Circular Reasoning: Uses the conclusion as a premise
  • False Dichotomy: Assumes only two options exist when more are possible
  • Sampling Flaw: Draws broad conclusions from unrepresentative samples
  • Ad Hominem: Attacks the person making an argument rather than the argument itself
  • Equivocation: Uses the same word with different meanings in premises and conclusion
  • Overlooking Alternatives: Fails to consider other possible explanations

Strategy:

  1. Identify the conclusion and premises
  2. Determine what the author assumes
  3. Identify what the author overlooks or fails to establish
  4. Match to common flaw patterns

Category 4: Inference Questions

🔎 Must Be True/Inference Questions

Question Stems:

  • "If the statements above are true, which one of the following must also be true?"
  • "Which one of the following can be properly inferred from the passage?"
  • "The statements above, if true, best support which of the following?"

What They Ask: What conclusion can be drawn with certainty from the given information.

Strategy:

  1. Note: These questions have NO argument—just facts
  2. Accept all stated information as true
  3. Look for what MUST be true, not what COULD be true
  4. The correct answer is often a conservative statement
  5. Eliminate answers that go beyond the information provided
  6. Watch for conditional logic (if/then statements)

Category 5: Main Point Questions

🎯 Main Point/Main Conclusion Questions

Question Stems:

  • "Which one of the following most accurately expresses the main conclusion of the argument?"
  • "The main point of the argument is that..."

What They Ask: Identify the primary conclusion of the argument.

Strategy:

  1. Look for conclusion indicators (therefore, thus, so)
  2. Ask "What is the author trying to convince me of?"
  3. The main conclusion has support but doesn't support other claims
  4. Test by asking "Why?" about each sentence—the main conclusion is what others answer

Category 6: Method of Reasoning Questions

🔄 Method of Reasoning/Argument Method Questions

Question Stems:

  • "The argument proceeds by..."
  • "Which one of the following describes the technique of reasoning used above?"

What They Ask: Describe HOW the argument makes its case (the argumentative strategy).

Common Methods:

  • Providing a counterexample to refute a claim
  • Drawing an analogy between two situations
  • Appealing to an authority or expert
  • Citing statistical evidence
  • Identifying a logical inconsistency

Additional Question Types

  • Parallel Reasoning: Find an argument with the same logical structure as the stimulus
  • Principle Questions: Apply or identify a general rule that governs the argument
  • Paradox/Resolve: Explain an apparent contradiction in the facts
  • Role of Statement: Identify the function of a specific sentence in the argument
  • Point at Issue: Identify what two speakers disagree about

Essential Logical Reasoning Strategies

Beyond understanding question types, these strategic approaches will improve your accuracy and speed.

The 6-Step Method for Every Question

  1. Read the Question Stem First: Know what you're looking for before reading the passage
  2. Read the Passage Actively: Identify conclusion, premises, and assumptions as you read
  3. Simplify and Paraphrase: Put the argument in your own words
  4. Predict the Answer: Before looking at choices, anticipate what the correct answer should do
  5. Evaluate All Five Choices: Never stop at the first answer that seems right
  6. Eliminate and Select: Use process of elimination to find the best answer

Common Wrong Answer Patterns

Recognizing wrong answer patterns accelerates your elimination process:

⚠️ Common Wrong Answer Traps:

  • Out of Scope: Introduces information not discussed in the argument
  • Extreme Language: Uses absolute terms (always, never, only, all) when the argument is more moderate
  • Reversal: Flips the logic of the argument (if the argument says A→B, the answer says B→A)
  • Half-Right: Part of the answer is correct, but another part is wrong
  • Attacking Premises: Questions the truth of stated evidence (never correct)
  • Right Answer, Wrong Question: Would be correct for a different question type

Conditional Logic Shortcuts

Many Logical Reasoning questions involve conditional statements (if/then relationships). Understanding conditional logic is essential:

Conditional Logic Formulas:

If \( A \), then \( B \) can be written as: \( A \rightarrow B \)

Contrapositive (always true): \( \neg B \rightarrow \neg A \)

If NOT B, then NOT A


Common Errors (NOT valid):

❌ Converse: \( B \rightarrow A \) (NOT necessarily true)

❌ Inverse: \( \neg A \rightarrow \neg B \) (NOT necessarily true)

Conditional Logic Example:

Statement: "If you study consistently, then you will improve your LSAT score."

Symbolic Form: Study Consistently → Improve Score

Valid Contrapositive: Did NOT Improve → Did NOT Study Consistently

Invalid Converse: Improve Score → Study Consistently (NO—you might improve for other reasons)

Invalid Inverse: NOT Study → NOT Improve (NO—you might improve without studying)

Common Mistakes to Avoid

Even strong test takers make predictable errors. Avoiding these mistakes will immediately improve your score:

Top 10 Logical Reasoning Mistakes

  1. Not Reading All Answer Choices: Always read all five options before selecting. The first "good" answer may not be the BEST answer.
  2. Bringing Outside Knowledge: Base your answer only on information in the passage, not on what you know about the topic.
  3. Questioning Premises: Accept all stated facts as true on the LSAT, even if they seem dubious.
  4. Confusing Question Types: Each question type requires a different approach. Don't treat all questions the same.
  5. Failing to Pre-phrase: Predict the answer before looking at choices to avoid being misled.
  6. Misidentifying the Conclusion: The conclusion isn't always the last sentence. Look for indicators and ask "What's the main point?"
  7. Rushing Through the Passage: Spending 10 extra seconds understanding the argument saves 30 seconds on answer evaluation.
  8. Falling for "Sounds Right" Answers: Wrong answers often use language from the passage but don't actually answer the question.
  9. Ignoring Scope: The correct answer must match the scope of the conclusion (not too broad, not too narrow).
  10. Poor Time Management: Don't spend 3 minutes on one question. Skip difficult questions and return if time permits.

  6. Revisit Difficult Questions: Attempt them again after a few days

Time Management Strategies

With 24-26 questions in 35 minutes, you have approximately 1 minute 20 seconds per question. Strategic time management is essential.

Time Allocation Guidelines

  • Easy Questions (40% of section): 45-60 seconds each
  • Medium Questions (40% of section): 1:15-1:30 each
  • Difficult Questions (20% of section): 2:00-2:30 each

Timing Strategies

✅ Smart Timing Approach:

  1. Do Questions in Order (Usually): LSAT questions aren't strictly ordered by difficulty, so working through in order is generally fine
  2. Skip and Return: If a question seems very difficult, mark it and move on. Return if time permits.
  3. Time Checkpoints:
    • After Question 8: ~10-11 minutes elapsed
    • After Question 16: ~21-22 minutes elapsed
    • After Question 24: ~33-34 minutes (1-2 minutes to review)
  4. Never Leave Blanks: If running out of time, quickly select answers for remaining questions
  5. Budget Extra Time for Complex Questions: Parallel Reasoning and Principle questions often take longer

Advanced Logical Reasoning Techniques

Once you've mastered the fundamentals, these advanced strategies will help you reach top scores.

The Negation Test for Assumptions

The Negation Test is the most reliable method for necessary assumption questions:

  1. Negate each answer choice (make it say the opposite)
  2. If negating the answer DESTROYS the argument, it's a necessary assumption
  3. If negating the answer has NO EFFECT on the argument, it's not necessary

Negation Test Example:

Argument: "The new marketing campaign will increase sales because it targets younger consumers."

Answer Choice: "Younger consumers respond well to this type of marketing."

Negation: "Younger consumers do NOT respond well to this type of marketing."

Result: If they don't respond well, the campaign won't increase sales → argument falls apart → this IS a necessary assumption ✓

Scope Matching

The correct answer must match the scope of the conclusion:

  • If the conclusion is about "some companies," the answer can't be about "all companies"
  • If the conclusion is about "increasing sales," the answer can't be about "maximizing profits"
  • If the conclusion is about "cause," the answer can't be about "correlation"

Pre-phrasing Technique

Before looking at answer choices, predict what the correct answer should accomplish:

  • For Assumptions: What unstated connection makes this argument work?
  • For Strengthen: What fact would support the assumption?
  • For Weaken: What fact would undermine the assumption?
  • For Flaws: What does the author overlook or fail to establish?

Frequently Asked Questions

What is LSAT Logical Reasoning? +

LSAT Logical Reasoning is one of the core sections of the Law School Admission Test, consisting of two 35-minute sections with 24-26 questions each. These sections test your ability to analyze, evaluate, and critically examine arguments drawn from various sources including newspapers, magazines, and scholarly publications. The questions assess skills essential to legal reasoning including recognizing argument parts, identifying assumptions, evaluating evidence, and detecting logical flaws. Logical Reasoning represents approximately 50% of your total LSAT score, making it the most heavily weighted section of the test.

What are the main parts of a Logical Reasoning argument? +

Every Logical Reasoning argument has three main components: Premises (facts or evidence provided as support that must be accepted as true), Conclusion (the claim or statement being argued—the main point the author wants you to believe), and Assumptions (unstated connections between premises and conclusion that must be true for the argument to work). The fundamental formula is: Premises + Assumption = Conclusion. Understanding these elements is essential for answering all Logical Reasoning question types correctly, especially Assumption, Strengthen, Weaken, and Flaw questions.

How many Logical Reasoning sections are on the LSAT? +

The LSAT includes two scored Logical Reasoning sections, each lasting 35 minutes with approximately 24-26 questions per section. This means you'll answer roughly 48-52 total Logical Reasoning questions during your LSAT. Combined, these two sections represent about 50% of your total LSAT score, making Logical Reasoning the most heavily weighted component of the test. The LSAT also includes one unscored experimental section, which could be either Logical Reasoning or Reading Comprehension, but you won't know which section is experimental during the test.

What skills does LSAT Logical Reasoning test? +

According to LSAC, Logical Reasoning tests 10 core skills essential to legal reasoning: 1) Recognizing argument parts and their relationships, 2) Recognizing similarities and differences between reasoning patterns, 3) Drawing well-supported conclusions, 4) Reasoning by analogy, 5) Recognizing points of disagreement, 6) Determining how additional evidence affects arguments, 7) Detecting assumptions made by arguments, 8) Identifying and applying principles or rules, 9) Identifying flaws in arguments, and 10) Identifying explanations. These skills directly mirror the analytical abilities you'll need as a law student and practicing attorney.

What are the most common Logical Reasoning question types? +

The most common Logical Reasoning question types are: Assumption questions (necessary and sufficient), Strengthen/Weaken questions, Flaw questions, Inference/Must Be True questions, Main Point questions, Method of Reasoning questions, Parallel Reasoning questions, Principle questions, Role of Statement questions, and Paradox/Resolve questions. Each question type requires specific strategies and approaches. Assumption, Strengthen/Weaken, and Flaw questions together account for approximately 50-60% of all Logical Reasoning questions, so mastering these types is particularly important.

How do I identify the conclusion in a Logical Reasoning argument? +

To identify the conclusion, look for conclusion indicators like therefore, thus, so, hence, consequently, it follows that, clearly. The conclusion is the main claim the author is trying to prove—ask yourself "What is the author trying to convince me of?" The conclusion has evidence supporting it but doesn't support other claims in the argument. It's the answer to "So what?" after reading the premises. A helpful test: ask "Why?" about each sentence. The main conclusion is what other sentences answer. The conclusion isn't always the last sentence; it can appear anywhere in the passage. Pay attention to argument structure and logical indicators rather than position.

What is an assumption in LSAT Logical Reasoning? +

An assumption is an unstated premise that must be true for the argument to be valid. It's the missing link between the evidence (premises) and the claim (conclusion). The formula is: Premises + Assumption = Conclusion. Assumptions are what the author takes for granted without explicitly stating them. They're critical to understanding argument structure and answering many question types including Assumption, Strengthen, Weaken, and Flaw questions. To find the assumption, identify the gap between what's stated (premises) and what's concluded, then determine what must be true to bridge that gap. Assumptions can be tested using the Negation Test: if negating a statement destroys the argument, it's a necessary assumption.

How can I improve my Logical Reasoning score? +

To improve your Logical Reasoning score: 1) Master argument structure by learning to quickly identify premises, conclusions, and assumptions in every passage. 2) Learn to recognize each question type instantly and apply type-specific strategies. 3) Practice pre-phrasing answers before reading answer choices to avoid being misled. 4) Use systematic process of elimination and read all five choices. 5) Practice extensively with official LSAC PrepTests through LawHub, not third-party materials. 6) Review every incorrect answer thoroughly to identify error patterns. 7) Time yourself to build speed while maintaining accuracy. 8) Take full practice tests regularly to build stamina. Most importantly, focus on understanding WHY answers are right or wrong, not just memorizing patterns.

Where can I find official LSAT Logical Reasoning practice questions? +

Official LSAT Logical Reasoning practice questions are available through LSAC's LawHub platform at lsac.org/lsat/prep. Free Official LSAT Prep provides access to practice questions, drill sets organized by question type, and the authentic digital LSAT interface. LawHub Advantage ($115 for one year) includes 75+ official PrepTests with over 1,500 real Logical Reasoning questions from past LSAT administrations.

Always use official LSAC materials rather than third-party practice questions to ensure you're practicing with authentic LSAT question construction and difficulty levels.

Do I need to know formal logic terminology for LSAT Logical Reasoning? +

No, according to LSAC, you do NOT need specialized knowledge of formal logic terminology like "ad hominem," "syllogism," "modus ponens," or other technical terms from formal logic. The LSAT does not test your knowledge of logic vocabulary or require you to apply formal logical systems. However, you DO need a university-level understanding of basic concepts like argument, premise, assumption, and conclusion. The test focuses on your ability to analyze and evaluate reasoning as it occurs in ordinary language, not formal logic expertise. If you're unfamiliar with these fundamental concepts, LSAC recommends reviewing them in official publications like SuperPrep and SuperPrep II.
