    Literally just do some research. You'll get no where from getting people to answer your questions, have a google and see what you can find yourself, and if you can't find anything, only then ask:

    I looked online, did some research but didn't understand so I was hoping if someone did a walk through on here of the first question, then I would be able to do the other 20 questions by myself once I had understood the theory of it. So I wasn't just getting people to answer my questions, I was just hoping to gain some more understanding.

    Are you doing alevels then now? If you didn't do it at AS then I assume you'll do it at A level but I think we also did this at GCSE it's just recapping it but I'm not sure. That's okay, thank you and good luck to you for your alevels if that's what you're doing.

    My exam board is OCR. It's quite strange that you haven't seen it on any past papers though even if you have a different exam board, I would've thought it was a pretty staple thing to need to know.
