Should I read as much about a topic as I can?

Through borrowing or purchasing books that aren’t directly related to the course but is relevant…will this help me? Will it be a waste of time? I’m wary of the teachers not going through all the necessary information to get the best mark, which has happened to me before.

Bump.

Can you be more specific? What class do you have in mind?

(If your class has a textbook, you should read it. As a college student, I’m usually pretty screwed if I try to study from my lecture notes alone.)

I don’t live in the U.S. but it’s maths and there’s a simulations component of the course. As a general rule I use both notes and textbooks for the class, but I’m wondering if it’s worth it going beyond or around it using another book. I’m thinking it’ll get me higher grades as I average the equivalent of a B or C mark.
