I have no idea where this is supposed to go.

I'm going to be taking this class through my school soon.
(I'll just get to the point)
They will be giving us the ASE tests... I just tried a couple practice tests online and failed terribly. Any good websites or books you suggest?
I don't know much at all about cars other than how to make 302's go faster.

Also, I heard that right after passing the class, I can make about $25/hour. After the year and I become certified, how much could I be making then?(Not one specific job, but just in general)
