I can calculate it, but I need one key detail: how much the major test is worth toward the final grade (its weight). If your current 85 is your grade before that test, use this formula:

new grade = old grade × (1 − w) + test score × w

where w is the test weight as a decimal (20% = 0.20).

Examples:
- If the test is 10%: new = 85×0.90 + 40×0.10 = 76.5 + 4 = 80.5
- If 20%: new = 85×0.80 + 40×0.20 = 68 + 8 = 76
- If 30%: new = 85×0.70 + 40×0.30 = 59.5 + 12 = 71.5
- If 50%: new = 85×0.50 + 40×0.50 = 42.5 + 20 = 62.5

Tell me the test weight (or how your grades are calculated) and I’ll give the exact new grade.
