There are definitely some interns/residents that still post over here, myself included.
OP, I took it 5 months in to intern year, which I felt was perfect timing. I prepped by reading master the board and doing comquest. I think that's what most people do and end up doing fine. I would definitely recommend getting it over with during intern year so it's not lingering over your head. I'm glad I have it out of the way!
Currently waiting on my score, my test was like 33% OMM, had to do it over again i wouldn't have studied anything but saverese. Took it 4 weeks ago and I'm still salty as hell. I half wonder if they slipped me step 1 as one last mind F.
