realistically, how many hours of studying do you need to guaranteed pass a STEM class

[Altruist]

my advice here would be useless because 3 "pages" of your curriculum are harder to master than 200 pages of mine

i went through entire law school without a single "hm, not sure i get it" moment. it's all a matter of being efficient at storing information in your brain so that you can recall it when the professor just tells you a random subtitle in the book and expects you to reproduce it

make no mistake, there's still room for failing if it's obvious you are just parroting the book content without any understanding, but if you are not entirely braindead, that's not happening
