So I broke down and bought a 30 day subscription. My exam is on Tuesday.
Pros:
-The questions are completely different from USMLEWorld or Kaplan Qbank.
USMLEWorld - exhaustingly long descriptions, every laboratory test you could possibly imagine, often you will know the answer by the end of the stem but then they are really asking you about some obscure fact about the answer that's in your head. Answer choices are often so similar that it's hard to narrow them down.
Combank - exactly like COMLEX, short, straightforward questions. Answer choices are so different that you can often narrow it down to 2 choices if you're not sure. Questions aren't quite as vague as real COMLEX questions but there have been a few.
In my opinion this is the best value of Combank. Almost regardless of the quality of the questions and your score, I think it starts to get you back in that "COMLEX" mindset that you need to have for the real exam. USMLEWorld is great but I end up studying such inane details that I know will never show up on COMLEX, having now taken Steps I and II.
-On many answer explanations, the authors go to great lengths to tell you this is a high yield topic for COMLEX. I'll reserve judgment on this until I take the real thing, but if I could have just had this information and used it to study the day before the exam, it would be worth the price of admission.
Cons:
-lots of typos
-I have the distinct feeling that the Step 3 Qbank is really the Step 2 Qbank, plus a couple extra questions. SEVERAL answer explanations have mentioned something like "high yield for COMLEX 2". I think if they are going to charge the same price for all three Qbanks, they should at least have distinct questions. Keep this in mind if you just used it for Step II. You're going to end up paying twice for the same questions if you use it again for Step III.
-I'm through over half the questions, and the OMM questions have not been very good so far. The OMM questions on Kaplan Qbank for COMLEX Step I were better.
Overall, I think some improvements could be made, but they are on the right track.
