I have been using MedAngle for the past few weeks, and I must say it's a lifesaver. I'm the kind of person who could never start another topic unless I'm sure that I've retained enough knowledge from the previous topic. I used to resort to past papers to evaluate myself, but that could only be done after completing the whole module. With MedAngle, my problem's solution is relatively easy, I can test myself after studying each topic, and that's the best thing!
