Now you know why you need to go to college for four years just to start being an engineer!

If you want to get some college level engineering textbooks, you might look at used bookstores, I know the local "friends of the library" bookstore has used EE textbooks in stock for 50 cents a piece.

or just ask your engineering mentor...I'd be surprised if they couldn't find you something to read.
