Since calculus is one of the mandatory subjects for students studying engineering, science, technology, business related courses, most colleges in the United States have at least one calculus course. Students can get credit for the course in their college by taking the advanced placement(AP) tests for calculus (calc) conducted by the college board. Students who wish to get credits for only one semester calculus course can take the ab calculus exam of the college board. Though all students would like to get the best score possible, they would like to check the ap calc ab 2019 curve to find out the percentage of students who get different scores to find out if it is worth the effort.

The AB calculus exam covers fewer calculus topics like limits, functions and graphs, integrals, derivatives and their related applications. Like most normalized or scaled scores for the AP tests, the 2019 curve is having a bell like shape, with a larger number of students having average scores, and a smaller number of students have very high or very low scores. The score of the student for the curve is derived from the composite raw scores of the student, which vary between 0 and 108. There are multiple choice questions and free answer questions for the ab calculus test.

In 2019, the number of students taking the AP calculus tests increased by approximately 5000. The percentage of students whose score was three or more in calculus AB was slightly higher than the corresponding number of students in 2017 and 2018. The number of students having a score of 5 was 19.1%, 18.7% of students had a score of 4, 20.6% of the students had a score of three, while the number of students with a score of two and one was 23.3% and 18.3% respectively. Hence approximately 58.4% students who took the tests had a score of three or more.

Most colleges will recognize students who have a score of three or more in the AB calculus exam, to give the student course credits. The college board claims that a score of three means that the student is qualified, four is well qualified, and five corresponds to extremely well qualified. The curves of the scores are determined by the college board, so that the results are consistent, and to standardize them. Since the scores are considered equivalent to the college courses, the College board, is strict while grading the papers to maintain their standards.
