The Stanford engineering department, often regarded as the best in the world for computer science education, has made its core CS curriculum free for anyone with an internet connection. There are some catches, ie: you don’t get your assignments marked, you have no contact with the lecturer, but all the same, it is really a great resource. The material is very high-quality, professionally filmed lectures and a full compliment of handouts and course notes. It also does not even assume knowledge of programming – it teaches you right from the basics.
If I was trying to teach myself CS again, these courses would be an ideal place to start:
