Understanding Your AP Statistics Score
The AP Statistics exam is divided into two main sections, each accounting for 50% of the final composite score. However, calculating the final 1-5 grade isn't as simple as adding up points because the sections are weighted differently.
Section I: Multiple Choice (50%)
This section consists of 40 multiple-choice questions. Each question is worth 1 point. There is no penalty for guessing, so you should answer every question.
- Raw Score: 0 to 40 points.
- Weighting: The raw score is typically multiplied by 1.25 to calculate the weighted section score (Max 50).
Section II: Free Response (50%)
This section contains 6 open-ended questions. Questions 1 through 5 are shorter standard problems, while Question 6 is the Investigative Task, which requires more extended reasoning and synthesis.
- Scoring Scale: Each question is scored by readers on a scale of 0 to 4 (4 = Complete Response, 3 = Substantial, 2 = Developing, 1 = Minimal, 0 = No Credit).
- Questions 1-5: These are weighted equally. The sum of these scores is multiplied by approximately 1.875 (Max 37.5).
- Question 6 (Investigative Task): This single question carries significant weight (about 25% of the FRQ section or 12.5% of the total exam). Its score is multiplied by approximately 3.125 (Max 12.5).
Strategy Tip: Because the Investigative Task (Q6) is weighted nearly three times as heavily as a regular FRQ question, do not leave it blank! Even getting a partial score of 2 on Q6 is worth more than getting a 4 on Q1.
Typical Score Cutoffs
The College Board adjusts the curve slightly every year based on exam difficulty. However, historical data suggests the following composite score ranges (out of 100) for final AP scores:
| AP Score |
Composite Range (Approx) |
Recommendation |
| 5 |
70 – 100 |
Extremely Well Qualified |
| 4 |
57 – 69 |
Well Qualified |
| 3 |
44 – 56 |
Qualified (Passing) |
| 2 |
33 – 43 |
Possibly Qualified |
| 1 |
0 – 32 |
No Recommendation |
How to Use This Calculator
To get the most accurate prediction:
- Take a full practice Multiple Choice section and enter the number you got correct (do not subtract for wrong answers).
- Grade your Free Response questions strictly using a rubric. Be honest! It is often better to underestimate your FRQ scores (e.g., give yourself a 2 instead of a 3 if unsure) to provide a conservative estimate.
- Input your scores above to see where you land on the curve.
