sit in on classes at MIT without being a student

It was a Calc 2 class, and it basically covered what Calc 4 was at WPI. It was pretty cool, because I love algebra and calculus, though some of the multivariate stuff was over my head in my senior year of high school. The class was just as boring as any other math class, but I got the feeling things were probably moving twice as fast as at WPI, which is already twice as fast as most other schools.
