Cutoffs are estimates (3 public sources); College Board does not publish them. Method
Quick answer: on our estimate you need about 78 of 100 composite points for a 5 on AP Computer Science A, 59 for a 4 and 46 for a 3. With 70% of the free-response points, that is roughly 36 of 42 multiple-choice questions right for a 5 and 12 for a 3. Real cutoffs move a few points each year.
How the AP CSA exam is scored
The AP Computer Science A exam has 42 MCQs (1 hr 30 min, 55%) and 4 FRQs totaling 25 points (1 hr 30 min, 45%). Each section is converted to a weighted composite out of 100, and that composite is mapped to an AP score from 1 to 5.
| Section | Raw max | Weight | Composite pts per raw pt |
|---|---|---|---|
| Multiple choice | 42 | 55% | 1.31 |
| FRQ 1 Methods & Control Structures | 7 | 12.6% | 1.80 |
| FRQ 2 Class Design | 7 | 12.6% | 1.80 |
| FRQ 3 Data Analysis with ArrayList | 5 | 9% | 1.80 |
| FRQ 4 2D Array | 6 | 10.8% | 1.80 |
What score do you need for a 3, 4 or 5 on AP CSA?
These are estimated composite cutoffs out of 100, built from the median of public estimates. Use them as a target range, not a promise.
| AP score | Meaning (College Board) | Estimated composite |
|---|---|---|
| 5 | Extremely well qualified | 78+ |
| 4 | Well qualified | 59+ |
| 3 | Qualified | 46+ |
| 2 | Possibly qualified | 37+ |
| 1 | No recommendation | below 37 |
Multiple-choice questions needed for each score
| Target score | MCQ needed if FRQ = 50% | if FRQ = 70% | if FRQ = 90% |
|---|---|---|---|
| AP 5 (≥ 78) | not reachable | 36 / 42 | 29 / 42 |
| AP 4 (≥ 59) | 28 / 42 | 21 / 42 | 15 / 42 |
| AP 3 (≥ 46) | 18 / 42 | 12 / 42 | 5 / 42 |

How to raise your AP CSA score
- Write the method header exactly as given — rubric points are awarded per algorithm step, not for compiling code.
- One multiple-choice question is worth 1.31 composite points; one point on "FRQ 1 Methods & Control Structures" is worth 1.80. Spend practice time where a raw point buys the most.
- Plug in your practice-test numbers above after every full test — the "points to the next score" line tells you how far you are from the next band.
How this AP CSA calculator works
Each section's raw points are divided by the section maximum and multiplied by its official weight from AP Central. The weighted parts add up to a composite out of 100, which is compared with the estimated cutoffs above. See the full methodology.
