Question 1

What GPA do I need for GKS?

Accepted Answer

GKS's academic requirement is met by ANY ONE of these: a CGPA at or above 2.64/4.0, 2.80/4.3, 2.91/4.5, or 3.23/5.0; 80% or above on a 100-point scale; or a class rank within the top 20%. The 80%/CGPA figure and the top-20% rank are separate alternatives, so you only need one. These are the published GKS baseline figures; always confirm the exact requirement in the GKS application guidelines for your round.

Question 2

Is 2.91 out of 4.5 enough for GKS?

Accepted Answer

2.91 on a 4.5 scale sits exactly at the GKS baseline, so it reads as a borderline case rather than a comfortable pass. Because universities convert grades differently, double-check your school's own percentage conversion before you rely on a number this close. Enter your real GPA in the checker above to see where you land.

Question 3

Can I apply to GKS with a GPA below 80%?

Accepted Answer

You can still apply. A GPA below 80% (or the minimum CGPA) is under the GKS GPA figure, but GKS also accepts applicants ranked within the top 20% of their class, so if your university can certify a top-20% class rank, you may still meet the academic requirement on that basis. GPA is only one part of the application and conversions vary by school, so confirm your standing against the GKS application guidelines and your university's registrar before deciding.

Question 4

Does GKS accept top 20% class rank instead of GPA?

Accepted Answer

Yes. A top-20% class rank is a separate alternative to the GPA figure — 80% on a 100-point scale, or the minimum CGPA for your scale — so satisfying either one meets the academic requirement. StudySunbae checks the GPA figure only, not class rank. If your GPA is below the baseline but your university can certify a top-20% rank, you may still qualify; confirm it against the GKS application guidelines for your round.

Question 5

How do I convert my GPA for GKS?

Accepted Answer

Pick your grading scale and enter your GPA; the tool compares it to the GKS baseline using the GKS conversion table (the fixed Appendix A lookup in the GKS application guidelines, not a linear formula). The 4.0, 4.3, 4.5, 5.0, and 100-point scales are compared directly. A 10-point scale can only be estimated, so the result shows an “Approximation used” label; for that, the most reliable figure is the percentage your university's registrar records on your transcript.

Question 6

My transcript uses a UK, German, or 10-point scale. Can I still use this?

Accepted Answer

GKS recognises only the 4.0, 4.3, 4.5, 5.0, and 100-point scales, plus a top-20% class rank. It does not publish a conversion for systems like UK honours classifications, the German 1.0–5.0 scale, the French 20-point scale, or Russian and Central-Asian 5-point grades, so StudySunbae will not guess one. Ask your university's registrar for your percentage or a converted GPA on one of the accepted scales, then enter that here.

Question 7

Why does the checker show “borderline”?

Accepted Answer

“Borderline” means your number sits right at the edge of the GKS baseline rather than comfortably above it. Because universities convert grades differently, a slightly different conversion could push a borderline score just under the line. Treat it as a prompt to confirm your school's own percentage conversion before you rely on the result.

Question 8

Is StudySunbae an official GKS website?

Accepted Answer

No. StudySunbae is an independent project and is not affiliated with GKS, NIIED, or the South Korean government. It is an unofficial pre-check that helps you gauge your GPA quickly. It does not represent GKS and makes no admissions decision.

Question 9

Does StudySunbae save my GPA or result?

Accepted Answer

No. Your GPA, age, and TOPIK level are calculated in your browser and are not saved to a database or sent to analytics. The one exception is a share link: it encodes your GPA in the link's URL, so anyone who opens it — and the server that serves it — can read it. Your email is stored only if you opt in to deadline alerts.

Question 10

Does this checker guarantee eligibility?

Accepted Answer

No. A “Likely meets” result means your GPA alone looks to clear the baseline; it is not a guarantee. GKS selection also weighs your study plan, language ability, recommendations, and other requirements, and the final decision rests with GKS and the host institution. Use it as a first pass, then confirm everything else against the GKS application guidelines.
