How to convert marks to GPA?

Converting marks to GPA depends on your institution’s scale, but here’s the basic approach. Most U.S. schools use a 4.0 scale, where letter grades (A=4.0, B=3.0, etc.) or percentages map to specific points. For example, a 90-100% might equal an A (4.0), while an 80-89% could be a B (3.0) but ranges vary, so check your school’s grading policy first.

To calculate GPA:

1. Convert each course’s final mark to its GPA equivalent (e.g., 85% = 3.5).
2. Multiply each course’s GPA by its credit hours.
3. Add all those numbers, then divide by total credit hours.

Say you have two classes: a 3-credit course graded A (4.0) and a 2-credit course graded B (3.0). Your GPA would be:
(3*4.0 + 2*3.0) / (3+2) = 3.6.

For international conversions (like percentage-based systems to 4.0), tools like the WES iGPA Calculator or your target school’s guidelines can help. Keep in mind that some universities assess transcripts directly, so double-check their requirements or ask admissions staff if you’re unsure. A little legwork upfront avoids mix-ups later.
