How the AP CSP exam is scored
AP CSP is scored from a 70-question multiple choice exam (70%) and the Create performance task (30%), which since 2024 combines your submitted program and video with two written responses answered during the exam. The Create task rubric has six points across program purpose and function, data abstraction, procedural abstraction, algorithm implementation, and testing. Multiple choice includes single-select and multi-select questions.
| Section | Questions or points | Weight | Composite points per raw point |
|---|---|---|---|
| Multiple choice | 70 questions | 70% | 1 |
| Create performance task | 6 points | 30% | 5 |
Composite formula
Each section's raw score is turned into a share of the section's weight, and the shares are added. The result is a composite on a 0 to 100 scale, which is the same proportion as the College Board's raw composite for this exam:
composite = multiple choice / 70 x 70
+ create performance task / 6 x 30Put another way, one multiple choice question is worth 1 composite points, while one point on the create performance task question is worth 5. That ratio tells you where an hour of practice moves your score the most.
Estimated AP CSP score cutoffs
Cutoffs vary by year; these are estimates from released exams and practice scoring guides. The College Board equates each exam after it is given and does not publish the current year's cutoffs.
| AP score | Meaning | Composite needed (of 100) | Multiple choice alone, with the example free response |
|---|---|---|---|
| 5 | extremely well qualified | 73 | 53 of 70 |
| 4 | well qualified | 61 | 41 of 70 |
| 3 | qualified | 48 | 28 of 70 |
| 2 | possibly qualified | 36 | 16 of 70 |
| 1 | no recommendation | below 36 |
Worked example: the form defaults
The calculator starts at about 70% of the maximum on every part. Here is the full arithmetic for those numbers:
| Section | Raw | Calculation | Composite points |
|---|---|---|---|
| Multiple choice | 49 of 70 | 49 / 70 x 70 | 49 |
| Create performance task | 4 of 6 | 4 / 6 x 30 | 20 |
| Composite | 69 |
A composite of 69 is a 4 under the estimated cutoffs (a 5 starts at 73, so it is 4 points short). Holding the free-response scores fixed, 53 multiple choice correct instead of 49 would reach a 5.
Where to gain points on AP CSP
Because the composite is a weighted sum, every raw point has a fixed value, and they are not equal. On this exam a multiple choice question is worth 1 composite points and a create performance task point 5, so one extra rubric point there is worth about 5 multiple choice questions. Free-response rubrics award points for specific moves (a thesis, a labeled graph, a unit, a justification), so learning what the graders look for usually adds points faster than more content review. On multiple choice, the lack of a guessing penalty means every blank is a wasted chance.
What the score means for college credit
Colleges set their own AP credit policies. Most public universities grant credit or placement for a 3 on AP CSP; many selective private colleges require a 4 or 5, and some grant placement but not credit. The College Board's credit policy search lists each college's rule by exam. Scores stay in your account, and you can withhold or cancel a score before it is sent if you would rather a college not see it.
Predicted scores are estimates. Section weights follow the College Board course and exam description for AP Computer Science Principles; the composite-to-score cutoffs are estimated from released exams and change each year when the College Board sets the curve.
