I was in math methods but dropped down to general maths, I heavily regret that decision as general maths is way too easy aswell as math methods is a prerequisite for doing a bachelor of science majoring in physics. I'm planning on doing math methods units 3 and 4 next year but I'm worried that since I missed out on units 1 and 2, I'll be screwed. Is there like any courses or books that can teach me methods 1 and 2 at home or something? Any advice/help would be appreciated.
