About

Last updated: October 19, 2026

We designed and developed this website as a small team while studying at Middle East Technical University (METU).

Our aim was to help other students calculate their GPA (grade point average) and cumulative GPA (CGPA). metugpa has since grown to include course grade, final exam, financial and university admissions tools.

Grading systems in the calculator

Colleges use different letter grades, point values and course-repeat rules. Choose the calculator and settings that match your college.

1) AA/BA/BB grading system

The METU GPA Calculator uses AA/BA/BB letters on a 4.0 scale. Its grade-point table shows the values used in the calculation.

2) A+/A/A− and whole-letter grades

The College GPA Calculator calculates semester and cumulative GPA using credit hours and letter grades. It supports 4.0, 4.3 and 4.33 scales, whole-letter grades, and custom grade points.

A+ and A both count as 4.0 in the default profile. Other profiles assign 4.3 or 4.33 to A+. You can edit point values and include or exclude letters to match your college’s scale.

For cumulative GPA, choose whether retaking a course replaces the previous grade, counts both attempts, or uses the higher grade. Previous attempts must already be included in the GPA and credit hours you enter. Semester GPA uses the new attempts entered in the calculator.

3) A1/A2/A3 grading system

The A1/A2/A3 GPA Calculator uses a separate 4.0 grade-point table for this letter system. Check its values against your college’s current grading policy.

Each GPA calculator includes instructions and worked examples. Grade-point values are different from the scores out of 100 used to calculate an individual course grade.

Course grades and final exams

The Grade Calculator combines midterm, final exam and other assessment scores using their course weights. It also offers an optional estimated curve.

The Final Grade Calculator works backward from a target letter grade to find the final exam score you need. Add multiple midterms and other assessments, choose a grading scale, and adjust the letter-grade cutoffs to your syllabus. An optional curve lets you explore a different set of cutoffs.

Curve results use a simplified model and are estimates. Colleges and instructors may apply different cutoffs, rounding, minimum-final requirements and repeat rules. Our results do not replace official grades or academic records.

Our other student tools

You can also use our Percentage Calculator and financial calculator.

Our YKS score calculator estimates scores and rankings from TYT, AYT and English YDT net scores. Our university and program guide lets you compare previous admission scores and rankings, or explore programs using a ranking you already know. “Kaç Net Gerekir?” shows the last admitted candidate’s subject-level net scores where data is available. These admissions tools are currently available in Turkish.

The guide uses YÖK Atlas and ÖSYM data. Calculated scores and rankings are estimates; past admission results do not guarantee admission this year. Check the current ÖSYM guide and program requirements before making your preferences.
