I saw a video where the speaker said maths is not memorisation and whilst I would agree for a majority of problems. Since finishing my first year studying a mathematics undergraduate degree I've been exposed to countless theorems, lemmas and corollarys, especially within analysis and linear algebra etc. It has been feeling like I'm just trying to memorise these theorems and i have been struggling to apply them in tests and questions and even understand them full stop!
I don't whether this means my fundamental skills are lacking or whether I'm going about it the wrong way, I really enjoy the subject but I'm struggling to wrap my head around parts of it and when I do since theres lots more theorems/lemmas the old ones just leave my head.
Some advice would be greatly appreciated.
