In high school and during my attempt at attending a university, I barely even tried. I always thought of myself as “bad at math,” although I know realize it’s a matter of study and effort.

I dropped out after a year, and I’m now 25. I want to take a physics and astronomy pre-major program to transfer to a university and get my bachelor’s.

What’s the best way to study in preparation for math and physics? I really need to brush up on algebra and trig, my fundamentals are lacking.
