Hello, I'm studying Mathematics, Applied Mathematics and Physics at something roughly slightly less detailed than a-levels (Leaving Certificate). The applied mathematics isn't a problem at all, and the "understanding" clicks properly for me. However, in mathematics I find that it sometimes comes down to memorizing methods than a true understanding. I don't want to go into college level detail, and we haven't started Calculus yet (we will be doing it soon). I'm just looking at general pointers for going into slightly more detailed mathematics, with more opportunity for understanding at roughly the A-level/High School level. I've looked around and haven't seen anything specific to this, sorry if I'm wrong.
