Watch Mr Bruff on You Tube and if you can afford it down load his book (Β£5 ish) from his website.
Do use the revision guide for the board you are doing, I also did this:
Mind map for each paper - what each question was about and what I had to do in each.
Mind map the technical devices.
Mind map sentence structure.
Make a chart up with the terms I needed to know, what they meant, and how they effected the reader
Use Index cards to self test and also revise in spare time (ie waiting at the bus stop or travel time).
Read across the centuries that the exam would cover, and also newspapers/magazines to analyse how they were designed and the flow of the piece.
Learnt the discourse markers and how to look for inferred meaning which gives you extra marks; also the pyramid type marking scheme (ie to get a base level you need to use paragraphs and thus can move up to the next level).
I also would pick a page from any book and use it l like an exam text.
I hope that helps.
