I matched with COMLEX scores only. I actually think it is getting tougher. My prelim year has 4 months of wards and 3 ICU months at a small community program. The categorical residents are almost all IMG's and FMG's. All the prelims this year are american grads (8 MD 3 DO). 2 going into derm (1 at mayo clinic), 2 rads, 1 ophtho, 2 PM&R, 2 anesthesia (in NYC and cali).... cant remember the rest. So to me it seems getting a prelim med spot is harder than an advanced in some cases given the gap in "desireable grads" between prelim and categorical. Not really an easy year by any means, and it still seems to be filled primarily with high very quality prelims, in fact I 'm surprised they took me. All in all, it is more of a regional thing. All of my prelim and TY year interviews were fairly close to my school, except one. Good luck.
If I had known about the AOA/ACGME merger when applying last year I may have just done a DO traditional year. Worst case those tend to be available as a backup.
