in my high school senior year, you onl;y have to have 4 class credits, i could either do half day of high school, or they offer a boxes program, its a career technical institue as they all it. i get my four credits in the afternoon. so pretty much its i goto a diff building in the morn to a full size shop where they teach us about cars, touch the basics you need to be a tech. most of the kids there cant even do brakes, so me and a couple of my friends there are way ahead, and the teacher knows so he pretty much lets us do what we want. the week before last we pulled an engine and trans out of a 92 celica and swapped it in to a different celica, in 9 hours book time is 14.
