Took exam Dec. 28-29. Starting studying around mid-November, casually studying decks. I took the Board Busters book with me when I traveled for interviews and studied a bit more intensely Dec. 19-23 (decks, board busters, back exams going back to 1993, didn't bother with the really old exams from the mid to early 80s, Tufts Pharm) and then on the 27th, didn't take my board materials back home to study for Christmas since I knew I wouldn't have much time.
Here's the breakdown: Total Qs/my score/nat. avg.
OP: 59/51/41.4
Pharm: 42/34/28.1
O.S./Pain Control: 54/41/36.7
Ortho/Pedo: 67/43/48.7
Endo: 36/31/28.8
Perio: 63/53/43
Path/Radio: 58/45/41.7
Pt. Mgmt.: 60/53/42
Case Based: 100/76/67.9
Comp Score 87
I was really happy with my score given the amount of time truly devoted to studying. I was a bit nervous with case based as I had a few really bad radiographs that could have affected around 5-6 questions. Probably didn't do as well in pedo/ortho as I didn't devote a lot of time to ortho study, made a few dumb mistakes and some of the bad radiographs involved a pedo case.
My .02: Don't stress out over this test. Personally, I thought part 1 was a little bit worse as I felt so far removed from some of that material by the time I took the exam. Since most of this info was something I could relate to as it's pretty much all dentistry, I felt better prepared. Our class also took a fairly in depth oral path exam in Dec. as part of our oral medicine graduation requirement, which helped refresh material we learned the year before. As far as the questions regarding insurance and so forth, I'm glad our practice management instructor covered that well.
You've made it this far, you can pass and at this point, your total score will have absolutely no bearing on anything as it's P/F from this point on. If you get stuck, mark it and move on. Finish, review questions and move on. If you're on a roll, don't take that full hour break, take 10 min and have a snack, use the restroom if needed and get back on that horse while your brain is still in test mode. IMHO, I though day 2 was a bit tougher, but that was due to a few bad radiographs and a few subjective tx options that could definitely be argued, but overall, fair exam and one that you will glad to just be done with.
Good luck!
