Tips for math 53?

I’m taking math 53 with Canic next semester. I’m challenging myself to do well in this class since I’ve been getting mediocre grades in my math classes so far, and I know that I can do much better. Thing is, I don’t really know how to good in math classes, since my studying habits aren’t the greatest. Does anyone that has done well in math classes at Cal have any tips they can give me? Could be studying habits, or perhaps things you did before/during/after class? I’d be grateful for anything. Thank you!
