I took USMLE 2 on August 21 and COMLEX 2 on August 22. USMLE was a little over an 8 hour day including breaks, while COMLEX only took 5:15 including all three breaks.
As I expected from having taken Step 1 of both tests, USMLE 2 was superior to COMLEX 2. The USMLE had easy questions, challenging questions, and some VERY challenging questions, but what it did not have any WTF?! questions. Many times during USMLE I thought to myself how glad I was I had studied a certain topic because it enabled me to get some hard questions right (at least I think I got them right!). By the last block I felt like I was seeing sideways from fatigue, but when it was all over I didn't feel terrible about it.
The COMLEX 2 had three types of questions: 1.)questions that were ridiculously easy 2.)questions that I SWEAR had at least two equally correct answers 3.)WTF?! questions. I'm sure there weren't as many WTF ?'s as it seemed like while I was taking the test, but they
are heavily represented. These questions were over material that I would never have thought to study for a clinically-oriented examination. The WTF?! questions were similar to the ones you may remember from part 1, except I think that they were even more prevalent on part 2.
OMM was not too bad. The questions were either very easy or were of the WTF?! variety, with more of them being easy. I skimmed each chapter of Savarese (except chapter 10 and the sacrum chapter, which I read more carefully) to prepare. I would say I spent no more than 4 or 5 hours on OMM studying. I really don't think it would have helped me get more questions right had I studied more. I did no OMM questions to prepare.
To study I did all of USMLEWorld once, read Secrets twice, and read/skimmed Boards and Wards, which I had sorta read throughout year 3. I also reviewed just a few pages of some high-yield notes I had made when I studied for Step 1. Oh, I also took notes as I did UW, ended up with 32 pages of single-spaced, wide-margined notes. I reviewed these a couple times before my tests, and it seemed to be very helpful. Much more so for the USMLE, I'm sorry to inform you. I'm really not sure what source to recommend for COMLEX.
The good thing about COMLEX was the computer format. It was easy to navigate, pictures were good, and one day is SO MUCH better than two. I wish I could have highlighted and struck out text like I did with the USMLE, but the question stems were short enough that it didn't matter too much.
I'll update with scores when they are available in 7 months or whenever they get around to it.
