Question/Idea

I just took a practice test, and I was wondering if there was any way of seeing what individual questions I got wrong to understand how I got them wrong. If there's not already a system in place for that, I think there should be. I understand that Khan Academy tracks the topics linked to each question, but it's still helpful to revisit the initial question, so you can see how you thought about the question versus how you should have thought about the question. Additionally, I understand that once you take a practice test, you can erase your score and retake the test and knowing the answers to questions would be unbeneficial in that regard. However, I think that having an option to disregard that opportunity in favor of knowing the correct answer would be beneficial in itself.
