Mastery Study Mode

Mastery is a pretty cool feature we are particulary proud of, this is the concept: Where you're done practicing with a particular study material and want to figure out how knowledgeable you are on the subject, we look for study materials related to it and generate questions for you. For example, you're done studying a material on simultaneous equation, with mastery, you can practice questions from other simulatneous equation study materials. If you do well in the test, then you probably have good mastery of the study material.
