How the AP Environmental Science exam is scored
The exam is 2 hours and 40 minutes long. Multiple choice (80 questions) is 60% of your score and free response is 40%. The free response has three questions worth 10 points each. Each part is scaled by its weight and added into a composite out of 100, which is then converted to a score from 1 to 5.
What does it take to get a 5?
About 73 of 100 composite points, by our estimate. One way to get there is roughly 59 of 80 multiple choice questions right and 22 of 30 free-response points. A 4 takes about 59 points and a 3 about 49. In 2026, 13% of students earned a 5 and 69% earned a 3 or higher.
Where students lose points
The 80 multiple choice questions are 60% of the score. One free response asks you to analyze an environmental problem with a calculation: show every step and keep your units, since the setup earns points even when the final number is off. The design-an-investigation question wants a testable hypothesis and the variables you would control.
