I couldn't study too much for it due to other commitments, but I did fairly well.
Studying from the official books was enough and it is what I would advice to do since they are most similar to the questions you'll have on the exam.
For general tips, you can read the articles in this page (again, don't buy their books. The official ones are enough):
http://www.gmathacks.com/main/category-contents.htmland as a particular advice I would say to learn fairly well how to compute square roots of perfect squares from 10^2 up to 99^2 and the formula for the arithmetic sum starting from a number greater than one.
Other than this, the math required is not particularly advanced, but it may require you to reason a bit on the question.
Finally, you should quickly understand when a question is too difficult/strange for you so that you may skip it and save your time for the ones which you know.
