Mathematica for students through CITES is now available. It can be obtained here. The cost is $25 without media (45 MB download) or $30 with the CD. It expires on 8/25/12 at which time it needs to be renewed. It will be renewed most likely at $25 again and will last until the following August or September.
The most useful thing for me about these courses is the fact that I when I do need to use material from any of these classes, I can picture the problem in my mind and have little trouble setting up an answer. If I were armed only with equations and paper and pencil, I wouldn't even know where to begin.
