Frequently asked questions
Does every Thai university use this exact grade scale?
This is the standard Thai university 8-step 4.0 scale (A, B+, B, C+, C, D+, D, F). Most Thai universities use a scale similar to this one, but exact grade steps (whether B- or D- exist, for example) can vary slightly by institution and faculty — universities may vary, so check your registrar for the precise scale that applies to you.
Why do credit hours matter?
GPA is a weighted average — a course worth more credit hours contributes more to your overall GPA than a lighter course with the same grade, so entering accurate credit hours matters for the result.
