I sat the exam in June and came out of it very worried.
I think a key thing to do is to start at the end, ie the high mark questions. If you can get those sorted then it puts you under less pressure for the easier questions. Also know all the definitions inside out, and don't rely on having to look in the yellow book. This all helps to save time.
Know Traffic loads inside out, and how to do all the maths. I haven't got any feedback qu's now, but try to get hold of some Oxford or BAE stuff if you can.
Best of luck
