A+ certification study guides for linux

[cj]

Hi all

im going to be taking my A+ certification in a couple weeks and I am in 
need of a practice exam. I fould one (sybex test engine) and tried it on 
wine (because it was a windows program), but it didnt work.

The particular exam i am studying for has an incomplete study guide and 
the only practice exam i found was the one i mentioned. Does anybody 
know where i can go to download a practice exam or a complete study guide?

The test i am studying for is the depot technician (220-604)
