This probably won't apply to everyone though but this is to not waste your time

Don't study. Like not at all

I don't know. I mean, I don't even touch my books and I just draw but I still pass

Not really pass, like fail but not too low and still acceptable!

If you need to memorize something just stick to that

Don't study something you already know because it's kinda of a waste of time

I literally don't review at all. Just stock knowledge I guess

I mean, why review if tests are supposed to look on how much you remember through out the whole grading period?
