Frequently Asked Questions
Q. What is the difference between 4.5, 4.3, and 4.0 GPA scales?
On a 4.5 scale, A+ = 4.5. On a 4.3 scale, A+ = 4.3. On the US 4.0 scale, A+ and A both equal 4.0. Other grades (A-, B+, etc.) are typically identical across all three scales. Check your school's grading policy.
Q. What GPA do I need for a scholarship?
Most Korean universities require 4.0+ for full scholarships, 3.8+ for half scholarships, and 3.5+ for academic honors. Requirements vary — always check your school's official policy.
Q. How much does an A+ vs. A0 affect my GPA?
On a 4.5 scale, A+ (4.5) vs A0 (4.0) is a 0.5-point difference per credit. For a 3-credit course, that's 1.5 points in the weighted sum, which directly lowers your cumulative GPA.
Q. How do I account for a retaken course?
If retaking a course replaces your original grade, simply input the new grade. This calculator uses only the grades you enter.
Q. How do I handle Pass/Fail courses?
P/F courses are generally excluded from GPA calculations. Omit them from this calculator and only enter letter-graded courses for an accurate result.
Q. How does US GPA differ from Korean university grades?
The US typically uses a 4.0 scale (A=4.0, B=3.0, C=2.0). Korea commonly uses 4.5 or 4.3 scales with + and - increments. Select the matching scale for accurate conversion.

Expert Knowledge: GPA Calculator — 4.5 / 4.3 / 4.0 Scale + Scholarship Threshold Comparison
GPA (Grade Point Average) is the weighted average of letter grade points, each multiplied by its credit hours, then divided by total credits. Most Korean universities use a 4.5 scale; some (e.g., Korea University) use 4.3. For US graduate school applications, the WES (World Education Services) standard converts a Korean 4.0/4.5 to approximately 3.55 on the US 4.0 scale. To remain competitive for STEM graduate programs in the US, aim for at least 4.0/4.5 (~88%) on the Korean scale.
