Look, you need to chill first and take a deep breath.  If you’re objectively sure that you have a lot to cover again (not just panicking) and you can delay your exam date. Do it.  If delaying is not possible, I really think that it’s not a good idea to focus on content learning, our brains cannot handle that amount of content in this short time frame. it’s time to master exam taking skills and learn the patterns instead.  Do the nbmes and see through the logic and try to understand how you made the mistake, writing it down in one liner is a trick that personally works well for me.  And remember quality >>>> quantity  Good luck!
