*Math and Science Learning Materials*subforum and will learn from them when time allows. There's also something called the Khan Academy that has been recommended many times but I'm not sure if it would be adequate for academic preparation.

I'm a bit concerned about my lack of knowledge of geometry and proofs, but it looks like I still understand basic algebra, like rules of exponentiation, algebraic manipulation, etc. If I may be provided with more specific details about what to focus on to succeed in undergraduate Physics or Engineering, I'll be very grateful. Thanks.
