How the Composite Score Works
The AP Psychology exam is scored in two stages: first, your raw points from both Bluebook sections are combined into a single weighted composite percentage; second, that composite is converted to the 1–5 AP scale.
The exam splits its weight two-thirds to one-third across the two timed sections:
| Section | Component | Raw Points | Weight in Composite | Value of 1 Raw Point |
|---|---|---|---|---|
| Section I | 75 Multiple-Choice Questions (90 min) | 0–75 | 66.7% | of composite |
| Section II, Q1 | Article Analysis Question (AAQ) | 0–7 | 16.65% | of composite |
| Section II, Q2 | Evidence-Based Question (EBQ) | 0–7 | 16.65% |
Courselo calculates your estimated composite percentage () using the official section weights:
Zero Penalty for Guessing
Section I uses rights-only scoring: your raw MCQ score is simply the number of questions answered correctly out of 75. Blank answers and wrong answers both earn . Because every four-option question gives you a chance of earning of the composite by pure probability, leaving any item blank before the 90-minute timer expires always lowers your expected score.
Part-by-Part Independence on Section II
Free-response questions are graded analytically by AP Readers using a 7-point rubric for the AAQ and a 7-point rubric for the EBQ. Each part is evaluated independently:
- No holistic deductions: Spelling, typing speed, or paragraph elegance are never scored, provided the psychological meaning is clear and written in complete sentences.
- No domino penalties: On the EBQ, you can earn the Part A claim point even if your Part B and Part C evidence points fail. Conversely, you can earn the Part B(ii) or C(ii) reasoning and psychological application points even if you miss the Part B(i) or C(i) evidence citation point.
