The Qbanks
The overarching key to the dedicated period is to do as many practice questions as possible. Highly recommend completing your questions in TUTOR MODE, as you can see immediately why you got a question right or wrong and thus analyze your train of thought. If you got a question right, make sure that your reasoning was correct, not just a lucky guess.
Be diligent when reviewing your questions, but don't waste too much time going over all the answer choices. You will likely get tested on those different answers in a separate question, especially if they are high yield.
One important tip I would like to impart to you is to not get too stuck on content review. Of course, review topics you are weak on, but you know more than you think you do. Use your Qbank to continue to build your knowledge, not necessarily to test your knowledge. Test and time yourself using the NBMEs instead.
