I took the A+ a few years ago after a short training class, and passed it with higher marks than my instructor - who took it at the same time. It's not that I know more about computers than him - he's been doing this for a LONG time - it's that I know the test better. If you have a chance to take practice tests, do them over and over again so you get a feel for the way that questions are worded and the diagrams look. Like Jason425 said, the test is surprisingly hard for an entry level certification test.
