In a time when I didn't really know what to study/learn, MIT OCW gave me a huge repository of credible and well-structured information. The SICP and intro to algorithms/data structures lectures were among the coolest introduction to computer science/programming, their physics class helped me study for the MCAT in college and I recall they had a very intuitive intro calculus class that made it click for me in a way my own university's class did not. I've gotten dozens, perhaps even over 100 hours of entertainment and enrichment from their FREE resources. A truly awesome institution.
