Has anyone here used SuperMemo? I've been using Anki for past few months to study and I've got some good results but I'd like to make my learning even more efficient. Most resources on supermemo found on google are either written by Wozniak himself (creator of the program) or by some guy in masterhowtolearn blog. Do you have any experiences with it? Is learning the program and adjusting to the new workflow worth it or should I just stay with Anki?
