Letter scale
Standard US: A 93+, A- 90+, B+ 87+, B 83+, B- 80+, C+ 77+, C 73+, C- 70+, D+ 67+, D 60+, F below. Some schools use stricter scales (A starts at 95) or simpler ones (A 90+, B 80+, etc.). Check your syllabus.
Weights matter
A 95 on a 10% homework moves your final by 9.5 points × your-weight = 1 point. A 95 on a 40% final moves it by 38 points × 0.4 = 15.2 points. Focus prep effort on the high-weight items.
Curving
Some professors curve grades — adjust scores so the class average lands at a target. The math is the same; just apply the curve adjustment before entering scores here.
