One 2014 study of math and science AP courses showed that participation rates were 52.7% for AP Chemistry, 53.6% for AP Physics, 57.7% for AP Biology, and 77.4% for AP Calculus. [67] A 2017 study found similar participation rates (49.5% for AP Chemistry, 52.3% for AP Physics, 54.5% for Biology, and 68.9% for Calculus).
Each question answered correctly is worth one raw point, and there is no penalty for marking incorrect answers on the multiple-choice parts of the test; a student can answer all questions without a decrease in their score due to incorrect answers. This is parallel to several AP Tests eliminating the penalties for incorrect answers. To improve ...

An estimate of a one-dimensional parameter θ will be said to be median-unbiased, if, for fixed θ, the median of the distribution of the estimate is at the value θ; i.e., the estimate underestimates just as often as it overestimates.
