Everyone has different ways of learning, but I'd certainly suggest taking as many practice tests as you can. They give you you a decent understanding on how the questions might get worded in the 'actual test' and they also give you confidence on how to understand the correct answer.
The questions are multiple-choice based so that can help prompt your thining in those tricky moments when your mind goes blank.
Practise, practise and practise there's no short cuts.......
