>By the time I actually got to college I realized these techniques were not only more effective and enjoyable for me than sitting down in lectures, but that the vast majority of students never actually had to build these muscles to begin with.

This reminds me of a CS class I had in college with a bad professor. I knew the guy by reputation. We had like 4 tests that class, and the only time I stepped foot in the class room was to take his tests. I didn't bother with his lectures. I simply read the book and read the supplemental materials. The looks of outrage I got when it was revealed I got the highest grade in the class were priceless.
