This looks really interesting. How can I get in touch with you? (you can find contact details on my profile).
We're developing a learning platform for Anatomy, called Kenhub[0] and we've built our own quizzes with some aspects of spaced repetition already. We're looking at ways of taking it to the next level in terms of adaptability. We're also considering ways of re-purposing our original content to reach wider audience (we have thousands of our own anatomy illustrations and meta-data). Perhaps there's a way to collaborate with you?
