Hardest ap chem questions.
The passing rate for the AP Biology exam in 2021 was 59.2%. This is a fairly middle-of-the-road passing rate, as compared to other AP exams; therefore, we can assume that the AP Biology exam has a medium level of difficulty. Additionally, AP Bio's 5 rate was 15%. This is also middle-of-the-road, as far as 5 scores go.

Bond. Yes, AP Chemistry has consistently been ranked as one of the hardest AP classes. According to a survey done, class alumnae gave AP Chemistry a rating of 7.3/10 for overall difficulty , making it the 4th most difficult AP course (while AP Physics C Electricity and Magnetism, AP English Literature, and AP Physics C Mechanics being the top three). In the previous post, we talked about the Hess's law and how it can be used for measuring the enthalpy change (ΔH) for a reaction without making calorimetric measurements.. In short, the Hess's law is based on the fact that enthalpy is a state function, and therefore, ΔH rxn is the same whether the reaction takes place in one step or in a series of steps.AP chemistry is really not as hard as many people make it.
