I've done edx, Coursera, now mit ocw, khan academy, and plan on continued experimentation. The best tool overall I've found is Anki.

I've also tried to keep my learning carried with lots of reading. The most academic book of the year I had was"energy and civilization".

I would strongly recommend learning how to learn to help formulate a learning plan and making sure you get the right level of challenge.
