Has anyone taken nbme assessment exams? I want to take one, but I'm not sure which one is better 13 or 15?

start with 11 or 12...save 7,13, and 15 for later like RIGHT before your exam.

take 6 and 7 first. 7 is a bit tricky, but you'll do fine.

I actually just want to take one. I took the UW SA 1 and didn't do well. I want to take UW SA 2 a week before my scheduled date, and take one nbme in between now and then. I know the latest ones are the best ones to go with.
I am right now reviewing FA and UW qbank. I still have a lot of reviewing of the qbank to do, and I thought that would be better than NBME. Exam is in 4 weeks.
What do you think?
