🏫 Legacy O-Level Grade Converter – Bring Your O-Level Grades Into the Modern World
Remember O-Levels?
If you studied under the Cambridge GCE O-Level system — back before IGCSEs and A-Level reform took over the world — you probably have a transcript filled with A, B, C, D… maybe even an E.
But here’s the challenge:
“How do I explain these grades to a university in the U.S., Canada, or even modern-day UK systems?”
“What’s an O-Level ‘B’ worth in GPA?”
“How does it map to percentages or the 9–1 system?”
That’s where the Legacy O-Level Grade Converter comes in — your one-click solution to translate classic British grading into:
✅ Modern letter grades (A+ to F)
✅ Estimated percent scores
✅ Standardized U.S. GPA equivalents
📘 What Were the O-Level Grades?
The General Certificate of Education – Ordinary Level (GCE O-Level) was the standard for secondary education in many countries from the 1950s to the 2000s.
Grades ran from:
| Grade | Meaning |
|---|---|
| A | Distinction |
| B | Very Good |
| C | Good |
| D | Satisfactory |
| E | Minimum Pass |
| F/G/U | Fail / Ungraded |
In some systems, grades like “N” (for narrow fail) were also used — especially in Singapore and former British colonies.
🔁 Why Convert O-Level Grades Today?
Because many students, educators, and professionals still rely on O-Level transcripts for:
📄 University applications (especially adult learners)
🏢 International job applications
🇺🇸 Converting to U.S.-style GPA or percent systems
🎓 Academic equivalency evaluations
And let’s face it: most modern systems don’t even know what an O-Level “E” means anymore.
