I concur, you have years (plural) to go before you legitimally have the words master tech associated to your name.

Being a good mechanic is nothing that a book, computer and an instructor is going to give you in a short period of time.

You will also need to have a intuitive knack for this kind of stuff before you even start to learn what you will need to know.

Rotary7 pretty much hit the nail right on the head. Hell, I can do a pretty good alignment on a car with some string, a tape measure and some basic tools so you had better get past the idea of always having an expensive computerized machine to do all of your hard work for you.

Good luck.
