Frequently Asked Questions

How is GPA calculated?
GPA is a weighted average: multiply each course's grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0) by its credit hours, add those up, and divide by total credit hours. Example: an A in a 3-credit course and a B in a 4-credit course gives (4.0×3 + 3.0×4) ÷ 7 = 24 ÷ 7 ≈ 3.43.
What is the difference between weighted and unweighted GPA?
Unweighted GPA caps at 4.0 — every A is worth 4.0 regardless of course difficulty. Weighted GPA (often on a 5.0 scale) adds a bonus, usually +1.0, for honors, AP, or IB courses, so an A in AP Chemistry can be worth 5.0. Colleges often recalculate to their own scale, so both numbers matter.
What is a good GPA?
It depends on your goals. A 3.0 is generally considered solid, 3.5+ is competitive for most colleges and scholarships, and 3.7+ opens doors at selective schools. Context matters too — admissions officers look at course rigor and trends, not just the number.
Does an A+ count more than an A?
On the standard 4.0 scale used here, both are worth 4.0. Some schools use a 4.3 scale where A+ earns extra — if yours does, this calculator will slightly understate those courses. Check your school's handbook for its exact scale.
How can I raise my GPA?
Recent grades carry real weight in your cumulative average because every new credit dilutes old ones. Retaking a course you failed can help if your school replaces the grade (policies vary). The fastest lever is earning A's in high-credit courses this term — model scenarios above to see the effect.
Will this match my school's official GPA?
Very closely, if your school uses the standard scale (A = 4.0, A− = 3.7, B+ = 3.3, and so on). Schools with custom scales, 4.3 A+ values, or grade-replacement quirks may differ slightly. Use this for planning; your transcript is the official record.
