OT, but 7 weeks at the Middlebury Summer Languages program let me go from zero French to placing into third year French when I returned to my... um, "full-time" college the following fall. (After fighting them because they initially insisted I couldn't have progressed beyond a second year placement.)

Abilities and performance varied significantly, but the program let you make rapid progress if you were of a mind to.

If I may ask (in part because I consider returning to that area of Vermont), how did you find the Computer Sciences program?
