First nbme. Give me tips.

Hey everyone, I am going to attempt my first nbme. Will start with 25 or 26. Any tip is welcome. I looked up and there are 200 questions. Any one has any tips on how to solve them by making 10 blocks? So I should be able to cover it in 5 hours ? Am I supposed to take breaks in between or what. I want to closely match to exam style since I am not very well prepared right now and need to revise a lot of stuff but taking in one nbme to just check how's it like and what are my weak points.

How much time should I give in solving and then reviewing it.
