AP Calculus BC Score Calculator
Enter your multiple-choice and free-response points
Frequently Asked Questions
Same format as Calc AB: 45 multiple-choice questions (54 composite points) and 6 free-response questions worth 9 points each (54 composite points), for a total composite out of 108. BC has a more lenient curve than AB because the content is harder.
Because BC's curve is more forgiving, a composite around 61 or higher out of 108 typically earns a 5 — noticeably lower than the ~77 needed on AB. A 4 usually starts around 46.
Yes — College Board reports a separate 'AB subscore' covering only the AB-level content (roughly 60% of the BC exam), scored on the same 1-5 scale. This calculator estimates your overall BC score, not the AB subscore.
No. College Board does not publish the current year's exact cutoffs before scores are released. This calculator uses recent historical data for an estimate.

Approximate AP score cutoffs (recent years)
| AP Score | Composite (out of 108) |
|---|---|
| 5 | 61+ |
| 4 | 46–60 |
| 3 | 33–45 |
| 2 | 22–32 |
| 1 | below 22 |
Notice how much lower BC's cutoffs are than AB's despite the identical 108-point scale — BC students tend to be a stronger, more self-selected group, but the exam content is also harder, so College Board sets a more forgiving curve.
