How accurate is this AP Calculus AB estimate?

The composite uses the official 1.2 multiple-choice multiplier and full free-response points. The 1 to 5 mapping is an estimate since College Board sets and doesn't publish yearly cutoffs.

Multiple choice correct (out of 45)

Free-response points (out of 54)

AP Calculus AB splits evenly between 45 multiple-choice questions and six free-response questions, each half worth 54 points on a 108-point composite. This calculator scales your multiple choice the way the College Board does and adds your free-response points to estimate your 1–5.

How AP Calculus AB is scored

Multiple choice is multiplied by 1.2 to reach 54 points; the six free-response questions (9 points each, 54 total) count directly.

MC scaled = MC correct × 1.2 (max 54)
FRQ = free-response raw points (max 54)
Composite = MC scaled + FRQ (out of 108)

Section	Raw	Weight
Multiple choice	45 questions (Part A + B)	50%
Free response	6 questions × 9 points (54)	50%

Composite score to AP score (estimated)

College Board doesn't publish official cut scores, and they move each year. These commonly cited estimates are what this calculator uses.

AP Score	Composite (out of 108)
5	75 – 108
4	60 – 74
3	45 – 59
2	32 – 44
1	0 – 31

Worked example

30 of 45 multiple choice and 32 of 54 free-response points:

MC = 30 × 1.2	36
FRQ = 32	32
Composite = 36 + 32	68 → score of 4

Calculator and no-calculator sections

Both sections split into a no-calculator part and a calculator-allowed part. On multiple choice, Part A (30 questions) is no-calculator and Part B (15 questions) allows one; on free response, two questions allow a calculator and four do not. All 45 multiple-choice questions are pooled into the same 54-point scaling regardless of part.

Frequently asked questions

What do I need for a 5 in AP Calculus AB?

Around 75 of 108 composite on these estimates — you can miss roughly 30 points and still earn a 5. The exact line shifts each year.

Is there a guessing penalty?

No. There's no deduction for wrong answers, so answer every multiple-choice question.

Does the same calculator work for Calc BC?

BC has the same section structure and scaling, but different content and cut scores. Use a BC-specific tool for that exam.

How accurate is this estimate?
