I tried the approach of reading the question first on my last NBME few days ago. I read the last few lines first and then skimmed, I lost 10 points from my previous NBME and UWAS2. On those 2 assessments, I didn't use this approach. I took the last NBME in the evening few hours before bed time that maybe another reason for losing 10 points, but I wasn't tired. I didn't have timing issue and didn't think the NBME was that hard either. It showed couple subjects I was good at on previous NBME a month ago, now at borderline on this NBME. I was hoping for my NBME score to go up after working on my weak subjects, but instead I was devastated with 10 points drop. 10 points is too much...
I'm planning to retake this NBME in few days and not use the approach of reading the last line first to see what the NBME score will be this time since I haven't gone over the answers yet.
