The thing with math is that you remember it only if you regularly practice it.
I have some great references which I suggest for timely repetitive referencing.

You can refer textbooks and solve questions to get a better grounding. But for now, having atleast a basic idea of the various concepts will suffice. πŸ€·β€β™‚οΈ
