I'm an Industrial Tech teacher and love this. I've said before on this site that kids are pretty much done with high school classes by the end of the sophomore year. Trust me, I love when freshman sign up for our classes because I know they are interested. If a senior signs up for Woods I, he is looking for a place to hide his last year.
Let the kids that just want to be done, be done and go work for McDonalds (not that there's anything wrong with that

). Let the kids who want to learn a trade begin learning that trade "seriously" so they are ready to work at age 18. And for the kids that want to go to a 4 year school, make the Junior and Senior year strictly college prep. Maybe that way college could get a little tougher and actually get the higher thinking they want to have.
