How to prepare for A-level chem P5?

[SadiaMaryam]

I've read the whole book and yet when I try to solve paper 5, its just like I'm gonna get a heart attack. I know nothing of that.
Can anyone help me how to prepare for it?
What should I read to get enough knowledge to solve this paper? Mere practicing from past papers isn't enough.
I know its too late but InshAllah, I can still do it. Any tips?
