It's probably not a big deal but I dont want to wait until oct 7th to get my score if I take it early August. In the long run it may not matter. Tricky part is, they were very vague on why they were dropping 2 questions per block. So maybe the questions will be even longer?? Who knows.
I agree that it was a bad time for NBME to do this. Maybe they have their reasons, but it seems like Feb-March when people who are taking step 2 don't really care about their scores coming back would be a better time to delay scores than in August, when people are hoping to have scores back for residency apps. It might not be that bad though, I heard a lot of residency programs don't look at apps until Oct/Nov, so your scores might be ready before they look at your app.
