make sure you are positive you want to do it. I pissed away six months tuition at an auto school to find out it sucks and I am much happier working my "day job" and playing the old fashioned back yard mechanic at home.
My suggestion is to just buy an old beater and fix it up in the back yard yourself. that way you can take your time on it, since it is not your primary car. And if you f*ck something up, no big deal.
