Math suggestions

[Angrboda]

A large part of math is training your brain how to think properly. There is no substitute for doing the work.

I never did the work because I was bright enough to pass the tests without doing the work. I would just absorb the concepts and improvise the supporting bridges.

For example, I never worked through the trigonometric identities. So even in Differential Equations, if I needed a bit of trigonometry, I would invent it on the hoof from sin^2 x + cos^2 x = 1. This basically doomed my later math career.

I suggest you do the work.
