Enter each course with its grade and credit hours to get a properly weighted GPA. Weighting matters: a four-credit course moves your average four times as much as a one-credit one, which is why the unweighted mean of your grades is usually the wrong number.
GPA is a credit-weighted mean, not a plain average of your letter grades. Multiply each grade's points by its credit hours, sum, and divide by total credits. An A in a 4-credit course contributes 16 points and a C in a 1-credit course contributes 2; together that is 18 over 5 credits, a GPA of 3.6 — not the 3.0 you would get by averaging A and C.
The practical consequence: your large courses dominate. A poor grade in a 1-credit seminar barely registers, while the same grade in a 4-credit core course is four times as heavy.
Credit-weighting is what this does. The other sense — adding a bonus for honours or AP courses, so the result can exceed 4.0 — is a high-school convention and varies wildly between schools. This calculator uses the standard 4.0 scale with no course-difficulty bonus.
A- is 3.7 at most US universities, 3.67 at some, and plenty do not use plus and minus at all. Outside the US the scales are entirely different — the UK uses classifications, Germany a 1-to-5 scale where 1 is best. Check your institution's own table before using any figure in an application.
Multiply each course grade point by its credit hours, add those products, and divide by the total credits. An A in a 4-credit course contributes 16 points; a C in a 1-credit course contributes 2. Together that is 18 points over 5 credits, a GPA of 3.6.
Two different meanings are in circulation. Credit-weighting, which this does, accounts for course size. The other sense adds a bonus for honours or AP courses and can exceed 4.0. This calculator uses the standard 4.0 scale without course-difficulty bonuses.
Yes. A- is 3.7 at most US universities but some use 3.67, others do not use plus and minus at all, and many countries use entirely different scales. Check your institution before relying on any figure for an application.
