>>11063257>linear algebrathey don't teach this at any highschools anywhere in europe or america, what you learn in multi is not linear algebra its the tools necessary to do calculus with vector valued functions and nothing more.
>calculusRead the post more closely faggot, in America you can get AP credit for Calc and still end up needing to take Calculus II, many students do not get the requisite AP credits so they take it anyways during freshman year. It is also a weed out course because integration requires discerning which integration techniques to use in what order and remembering a large number of relationships between functions while derivatives only require very basic algebraic proficiency.
>physiologyis not the physiology you're taught during AP bio i'm talking about junior and senior level physiology which Pre-meds, Neuro, Physio and Organismal biologists take which would rape most STEM majors given the volume of information and the causal inference required to do well on detailed exam questions. None of the courses are particularly hard, I don't find those 3 difficult to develop intuition for but they do tend to filter out people who have poor spatial reasoning, very bad working memory and poor study habits.
