CGPA → 100-point conversion from Appendix A of the GKS Application Guidelines, a fixed, non-linear lookup, so read your scale's row rather than estimating with (GPA ÷ max) × 100. The highlighted 80 row is the eligibility baseline; there are no rows below it because 80 is the GKS academic floor.

What GPA do I need for GKS?

The GKS academic baseline is a 100-point score of 80. On the table above that's a CGPA of at least 2.64 (4.0), 2.80 (4.3), 2.91 (4.5), or 3.23 (5.0). GKS counts your grades as meeting the requirement if you satisfy any one of these routes:

  • a CGPA that reaches the 80 row (or higher) for your scale in the table above;
  • an equivalent of 80 or above on a 100-point scale; or
  • a class rank in the top 20% of your cohort.

Because any one route is enough, a CGPA that sits just under the 80 row is not automatically a rejection: a top-20% class rank can still meet the requirement.

What if my GPA scale isn't listed?

If your scale isn't one of these, don't invent a conversion. GKS asks for a school-certified converted transcript or a grade-conversion statement issued by the school that awarded your grades. Appendix A covers only the 4.0, 4.3, 4.5, and 5.0 scales; for anything else, third-party evaluations such as WES or Scholaro count only when that school certifies the converted figure. A self-made conversion does not. When in doubt, use the percentage or class-rank figure your school puts in writing.

Frequently asked questions

How do I read the GKS GPA conversion table?

Find the column for your CGPA scale (4.0, 4.3, 4.5, or 5.0), then the row your CGPA falls in. The left column is the equivalent GKS 100-point score. The highlighted 80 row is the GKS baseline: reaching it means your CGPA meets the minimum.

Why can't I just calculate my GKS score with a formula?

Because GKS uses an exact published lookup, not a formula. Appendix A maps each scale to the 100-point score in narrow, non-linear bands (the top bands are only about 0.04–0.05 wide), so a (GPA ÷ max) × 100 estimate can land in the wrong band. Read your equivalent straight from the table.

What CGPA meets the GKS 80% baseline on each scale?

On the table above, the 80 baseline starts at 2.64 (4.0 scale), 2.80 (4.3), 2.91 (4.5), and 3.23 (5.0). At or above these, your CGPA reaches the GKS minimum; below them, Appendix A publishes no score because it is under the eligibility floor.

Can I round up my GPA for GKS?

No. Report your CGPA exactly as your published transcript states it. Rounding up or recalculating to reach the 80 baseline can invalidate your application, because GKS reads the figure your school certifies, not one you adjust yourself.

Should I submit my GPA, a percentage, or a class rank?

Submit whatever your published transcript certifies. This table converts a 4.0, 4.3, 4.5, or 5.0 CGPA, but if your school issues a percentage or a class-rank figure instead, use that certified number. GKS also accepts a top-20% class rank as meeting the baseline.
