Help!

Basically, I'm doing the new edexcel spec and in the middle of doing my AS course

I love chemistry and it's a huge passion of mine, however the key points of information do not stick so my answers to test paper as good enough to get me past a D.. I understand most things but it's just remembering them

Anyone got any techniques! All are appreciated thanks!

p.s. I need help with the maths!
Probably best thing to do is remember them

Well, it's chemistry maths, no math maths!

I know all the equations I need to know but it's the whole putting them into different questions which I do not understand
