Comsae C: 410
Comlex 1: 660
Through trial and error, I have found that each person has to find what works best for them and stick with it. The problem is that there are so many companies popping up with new products that it becomes a guessing game. Luckily we have SDN to help each other out. For the most part, I felt like the reviews on SDN were very helpful. However, there are a few that I suspect are from the companies writing their own review. So here is what I did. I hope that it helps some of you in the future just as other reviews helped me.
DIT
I started with DIT and some UWorld. The only reason that I even started DIT was because my school made us buy it and I felt guilty for not doing it since I already paid a lot for it. This was my biggest mistake. It took me a little over 3 weeks to finish it. Somewhere towards week 3, I took COMSAE C and barely passed. This was my eye opener. I realized that even though they covered a topic, I was still getting questions wrong because they teach you to memorize small details. Even though I knew the details they were teaching, I didn't have the global knowledge to apply the details in slightly different presentations. I cannot recommend DIT to anyone. DIT is good for memorizing little details in First Aid, however I think that in order to do well on the board exams you have to acquire a very broad understanding of the material and while doing so the details will fall into place.
UWORLD
This is an extremely good quality question bank. Everyone already knows that it is the standard for the USMLE. Because I did DIT, I only had time to get through about 1/3 of UWorld.
COMBANK
I was not happy with the quality of COMBANK. The amount of errors in the material really started to get to me. I also started realizing that I wasn't learning a whole lot from each question. The explanations were poorly drafted or non-existent. It may be good for some people who are looking for a qbank for evaluating their knowledge level, but it certainly was not a good learning qbank. I found myself constantly looking up things that were blatantly wrong. The final straw came when there were questions drafted directly from First Aid 2012 that contained errata that was word for word, as if it was copied and pasted. It was very obvious that students were writing questions. They were writing them directly out of First Aid. At this point, I turned to SDN to look to see what else was out there. Someone spoke very highly of COMQUEST, so I gave it a shot.
COMQUEST
I did this bank for the last 2 or 3 weeks before my test. I really believe that this was the difference maker in my score. I cannot say enough about this qbank. Every question had a well thought out answer and discussion. This gave me the global knowledge to compare and contrast material. For example, in DIT or Combank I would pick up a few details about a specific gram negative rod in a certain presentation. But with Comquest, I found myself learning how to contrast all of the gram negative rods that fit that particular presentation. I could do about 100 questions a day at maximum, but I was learning so much from each question. Keep in mind that each explanation has about a page worth of information to read. It really made the information in First Aid pop out and the constant repetition helped me to start picking up details. I added in anything that wasn't in First Aid.
My particular Comlex was about 55% Micro. Micro was a weakness of mine until I did Comquest. The night before the test I read over my First Aid micro section with all of my Comquest notes. This ended up being huge for me. Another area that Comquest excelled in was Ethics and Medical Jurisprudence, which apparently has become a hot topic on the Comlex. I was very well-prepared for these areas on the test. There isn't a qbank out there that covers these areas better.
The development of the explanations is the what helped me so much. Their OMM section was great. I supplemented it with the questions at the end of Savarese.
Another thing that really impressed me was there customer service. I came across an error in an explanation and commented on it. Within 24 hours they had emailed me back and fixed the error. Combank never contacted me back and never fixed there bad questions.
If I had to do it again, I would have done UWorld and then Comquest twice. I will certainly be sticking with Comquest for COMLEX 2.
