A 2021 study of 10 million AP calculus and statistics students from 1997 to 2019, found that although female participation in these courses has increased significantly, the proportion of males to females at the top scores in the AP math exams is still substantial, though the proportion of males to females at the top scores has been slowly ...
The total composite score, which had a range of 3–45, was based on the individual scores of the verbal reasoning, biological sciences, and physical sciences, which each had a score range of 1–15. The writing sample, which consisted of two essays to be written within 30 minutes for each, was graded on a letter scale of J–T with T being the ...
