well im sure google could prolly help as far as maybe getting a study guide for it, but you could also pick up a copy of the latest a+ book
Study guide here:

Taking a look at some of the free study guides and materials from respected training vendors is a good way to see where you stand in terms of being prepared for the test.
Good luck.
