I've been using KA for their MCAT course for a while now - I'm a non-traditional student with no background in science. Practice questions for the MCAT are already limited and very hard to come by, so I appreciate that KA has some discrete and passage-based questions in their units. HOWEVER, I've stopped doing them because they NEVER actually correspond to the learning outcomes. It's INSANELY frustrating and makes me feel stupid. I also have trouble trusting lecture content when the discrete questions are so different - it makes me feel as if I'm missing something.

For example, I just finished EVERY LECTURE in unit 12: biological basis of behaviour (nervous system). I took quality notes, reviewed them over a few days, made my flashcards etc. I thought I'd be ready for the practice questions (which already concerned me because they're about the endocrine system when there were only two videos on that topic). NOT A SINGLE QUESTION reviewed content from the 22 included videos. STOP THIS MADNESS!! Who does this help? Why are you labelling practice questions for a given unit when they're completely unrelated to the content? I'm begging you - make better questions that test material you're teaching, or get rid of them, put them somewhere else where it doesn't make students like me feel like we've missed some fundamental topic.
