IB Subject Score (1–7) to GPA Converter – Decode Your IB Grades into U.S. GPA in Seconds
If you’re in the International Baccalaureate (IB) program, you know it’s no joke.
You’re writing essays at midnight. Juggling IAs, EE, CAS hours.
And after all that, your report card hits you with… a “6”.
Wait, what?
What even is a 6?
Is that an A? A B? What’s my GPA??
Welcome to the most confusing part of IB — the 1–7 scale that no one outside the program understands.
That’s exactly why we built the IB Subject Score (1–7) to GPA Converter — to finally bridge the gap between IB world and GPA reality.
🎯 What Is the IB 1–7 Scale?
In IB, each subject is graded from 1 (lowest) to 7 (highest).
| IB Score | Descriptor |
|---|---|
| 7 | Excellent |
| 6 | Very good |
| 5 | Good |
| 4 | Satisfactory |
| 3 | Mediocre |
| 2 | Poor |
| 1 | Very poor |
Great for international consistency.
Terrible when your college application asks for a GPA on a 4.0 scale.
🔄 Why Convert IB to GPA?
✅ You’re applying to U.S. or Canadian universities
✅ You want to compare your IB performance with national GPA averages
✅ You’re trying to predict college admissions outcomes
✅ You need clarity on where you really stand
Because here’s the truth:
A “6” in IB Physics is not the same as a “B” in Regular Physics.
It deserves GPA respect — and this converter gives it.
