That Exam Success book is very very helpful as it shows you the way they want answers written. Particularly the testing procedure, where they want you to write things such as seek permission to isolate, and test it's dead etc before, when you'd ordinarily just describe how to do the test.
Paying attention to the marks of each question is important as well, as is correct terminology throughout as incorrect terminology = incorrect answer. Read all questions properly and then go back through your answers ONCE (any more than that and you'll just change answers you don't know).
And good luck, I was told I'd passed after about 2 months, but didn't get my certificate for 3 months so was always unsure until then.
