Frequently Asked Questions
How do I calculate my GPA? +
For each course, multiply the grade points by the number of credits to get quality points. Add all quality points together and divide by total credits. Example: an A (4.0) in a 3-credit course = 12 quality points. Two such courses = 24 quality points ÷ 6 credits = 4.0 GPA.
What is a good GPA? +
On the US 4.0 scale: 3.5–4.0 is considered excellent, 3.0–3.4 is good, 2.5–2.9 is average, and below 2.0 may put you at risk academically. Many graduate programs require a minimum 3.0 GPA. Top employers and graduate schools often prefer 3.5+.
What is the difference between semester GPA and cumulative GPA? +
Semester GPA only includes courses from one term. Cumulative GPA covers all terms combined. To calculate your cumulative GPA, add up quality points from all semesters and divide by all credits attempted. Use this calculator for either — just add all your courses from any term.
How does the UK degree classification work? +
UK undergraduate degrees are classified as First Class (1st, 70%+), Upper Second Class (2:1, 60–69%), Lower Second Class (2:2, 50–59%), or Third Class (3rd, 40–49%). The final classification is typically based on a weighted average of your final year and sometimes second year marks. Exact boundaries vary by university.
