I think if there was a place that had the answers to self assessment services provided by the NBME, the NBME would probably shut them down, considering the questions themselves are copyrighted. If anything do NBME 4 pay the extra $15 at least you can see which ones you missed, and look up each of the answer choices, I took NBME 1 and did not find it helpful, 4 is much better in terms of learning from mistakes. I also heard that UWSA is not that predictive and is just a waste. Best of luck.
so thats only available for nbme 4? and it shows you what you missed but no answers? (thats def better than nothing!)
the only thing is, i don't want to waste the nbmes since there are only a few. is 4 the best? i'm trying to figure out what order to do them in.
