I hope not🙂 I just found out I've got to take USMLE step 2 as well, and I haven't even been able to schedule a date yet... I'm betting if you get scores in anytime before Nov-Dec you should be fine; just let the programs your interested in know when they come out if you're worried it might be missed. I've heard of many people putting taking the test off until nov-dec, so really shouldn't be a big deal unless you're counting on step 2 to get an interview (ie to make up for a sub-par step 1 score). GL!
