Test grade calculator

10-point: A=90+, B=80+, C=70+, D=60+. 7-point: A=93+, B=85+, C=77+, D=70+. On the 7-point scale, an 85% is a B; on the 10-point scale, it's a solid B or B+. Same knowledge, different grade.

True curving sets grades relative to class performance, not absolute standards. If the top score is 78%, that might become an A. The professor decides how to distribute letter grades across the score range. This helps when tests are too hard; it hurts when the class is strong.

Teachers offer extra credit to help students at the margin, not to reward those avoiding regular work. Completing all extra credit while bombing tests rarely saves a grade. Do the main work first.

(Correct answers ÷ Total questions) × 100. If you got 38 out of 50: 38 ÷ 50 × 100 = 76%.

On the standard 10-point scale, 75% is a C. On the 7-point scale, it might be a C-. On a curve, it could be anything from D to B depending on class performance.

Depends on the total and the scale. On a 50-question test with 90% A cutoff: 50 × 0.90 = 45 correct minimum, so you can miss 5. On a 93% scale, you can only miss 3.

Calculate: (Target grade × Total points − Current points) ÷ Final exam points. If you need 80% overall, have 300/400 points, and the final is 100 points: (0.80 × 500 − 300) ÷ 100 = 100%. You'd need a perfect score.

Depends on your teacher's rounding policy. Many round 89.5% up to 90% (A), but some keep it at 89% (B+). Ask your teacher—rounding policies vary by class and school. Some teachers round only at the semester, not on individual tests.

Unweighted: All classes use the same 4.0 scale (A=4.0, B=3.0, etc.). Weighted: Honors/AP classes get a boost (AP A = 5.0, honors A = 4.5). A 3.8 weighted GPA might be a 3.5 unweighted. Colleges recalculate using their own system anyway.

Technically yes, but it's uncommon and often needs to be approved. If they do, it's usually to make grading easier (lowering cutoffs), not harder. Changes typically apply to everyone equally. Check your syllabus—it might specify the scale as fixed.

Multiply each category average by its weight, then sum. Example: Tests 80% (weight 0.5), Homework 90% (weight 0.3), Final 70% (weight 0.2) = (80 × 0.5) + (90 × 0.3) + (70 × 0.2) = 40 + 27 + 14 = 81% overall.

Your worst test doesn't count toward your grade. If you took 5 tests and scored 80, 85, 90, 95, 60, the 60 is dropped and your test average is (80+85+90+95)/4 = 87.5%. Usually applies only to tests, not the final exam.

For weighted GPA, yes—an AP B+ might be 3.8-4.0 weighted vs 4.0 for regular A. For college admissions, they see both: rigor of your schedule AND your grades. An A in AP is best, but B+ in AP beats easy A in regular for competitive schools.

Check your syllabus for the final's weight. Common weights: 20-30% for semester finals, 40-50% for cumulative finals. If your final is 30% of your grade and you have 85% going in, scoring 100% raises you to 89.5%, scoring 70% drops you to 80.5%.

Passing is usually 60% (D) on the 10-point scale or 70% (D) on the 7-point scale. But 'passing' for prerequisites might require a C (70-77% depending on scale). And GPA requirements (sports, scholarships) might need higher. Know the specific threshold for your goal.
