Well cut the story short, I hate maths and I have an exam next week and because I hate it I haven't been doing well but last year I was getting level 6 and 7, but we did a practice exam and I got a level 4! HEEELLPPP!

What are exactly your problems? A week is not much... and if you want to revise all your lessons, better start as soon as possible.

What you can do, is post the questions you are stuck with. Take your book, do the work in it. You can post them in this thread itself, so that it doesn't confused other people viewing your thread.
