Students taking one of the slightly easier digital versions needed to earn 1–3 more points to earn a score of 3+, depending on their version, than students who took the paper exam on May 5. The net result for this year’s AP Physics 1 Exams is that out of 80 points possible, some of the digital versions were slightly easier than the paper versions and some of the digital versions were slightly more difficult than the paper versions.When exam questions prove easier, more points are required for each AP score, and when exam questions prove more difficult, fewer points are required on one version than another. Differences in the difficulty of specific questions.For sections of the exam that proved easier to take on paper, the paper exam requires more points for each AP score. For sections of the exam that proved easier to take digitally, the digital versions require more points for each AP score. Differences in the testing mode (paper or digital).Accordingly, to provide students with similar opportunities for success regardless of which version they took, each version of the exam had to be analyzed separately by psychometricians to identify its unique difficulty level so that standards for scores of 3, 4, and 5 could then be separately identified for each exam version. To protect exam security, many different exam versions were necessary. To support student access, different testing modes-paper and digital-were essential. By far the most challenging question on this year’s exam was Question 1 ~3% of students earned all 7 of 7 points possible.An impressive 25% of AP Physics 1 students earned 10–12 points out of 12 possible. AP Physics 1 students generally performed best on Question 2, Experimental Design.
