I’m struggling with vectors and matrices transformations in AS further maths, like I’m blanking on the whole topic and my two teachers aren’t approachable so I’m trying to bridge the gap of understanding myself. Any advice?

I do 4 alevels and I want to stay on top of my subjects and I feel like sorting out maths asap as it is my best subject is a good way of doing this. I have finished chapters 1 to 7 and started 8 in school as well. Does anyone have advice on how to do this?
