Hi- I was wondering if you could advise on how to find reputable explanations to the new NBME tests. I have taken 18 and 20 and I am just making a google doc with information about questions I have missed. I have found some information on 18 but very little for form 20. Also just curious on your thoughts about a 243 score on UWORLD practice test #1. I am only about 30% through UWORLD questions and was just wondering if that was a trusted score. Thanks!
