I did mine Jan 29, Scor reported Feb 20.
My score 93/226.
Concentrated on Kaplan books. Couldn't do any questions. Didn't get to read latter part of surgery and psychiatry.
My experience says if you get the concept right you could do well.
Questions definitely help, but you'll get better benifit from them if you know your material.
I am happy with 93/226, but I feel I could've done better if I read through the material twice.
