Ivy League classes online...

I thought this was an informative article, since many people may not be aware of the increasing online access to Ivy League presentations and class material. One example is from MIT:

An MIT initiative called "OpenCourseWare" makes virtually all the school's courses available online for free - lecture notes, readings, tests and often video lectures. Strang's Math 18.06 course is among the most popular, with visitors downloading his lectures more than 1.3 million times since June alone.

Other colleges are providing this type of material and it is a great way to learn more, I've used several to try to stay up to date when it comes to algebra.
