what r u weak in? im taking the exam around the same time as you!
The one thing for me is though I get very tired/bored even sometimes answering questions and that causes me to not pay attention to questions. When I go back and review I realize theres probably more than 10 - 15 questions I missed just due to lack of concentration.
you have to figure out what your weaknesses are. Use the score analysis and figure out what you are weak in.
How are you doing in your UWorld? how are you doing on the individuals tests and what is your overall performance? What does the graph tell you there, as in your weaknesses? Do these match to your weaknesses given in the NBME analysis?
I think you have more than enough time to work on your weaknesses. Dont stress! just focus!
good luck!
