My first 2 years of college were the worst waste of time and money. In high school I learned calculus, semiconductors, and assembly language. But course requirements make you start over at the beginning. Algebra, ohms law, and BASIC... Not to mention the other crap, like various writing/language, history, sociology... I suppose eventually you'll move up to challenging classes and projects. I didn't want to spend any more time or money, and eventually dropped out.
