An anonymous reader writes: I am a middle school math teacher and I also run a programming club. I recent completed my M.Ed in math education and was inspired to try to do the new GT online MS in Computer Science in a couple of years. I have some background in programming: 2 intro to comp sci course, Java, C++, Python, they main scripting languages and a bunch of math background. I also read through this great article on getting these pre-requisites completed through coursera but unfortunately you need to wait for courses to enroll. I would like to just learn these on my own time, no credit necessary. Suggestions?
