Buy a copy of First Aid or Step Up NOW. Become familiar with it...use it as you study for your MSII classes. Grab a copy of Pharmacology Recall and BRS Physiology and Pathology. Become familiar with the format of the review books by using them as a supplement to your course texts and notes...if you can use them in school when it comes time to study for COMLEX/USMLE you will be familiar with the books, you will have your own notes in there and you will feel less like you are trying to dig through mountains of material in a mere few weeks.
Oh, and try not to study the week leading up to the test. There is nothing you can learn 3 days before the test that will help you that much. At that point, relax. Also, don't to questions this late...any correct answer will give you false hopes and any wrong answer will panic you. The last week should be used for light review, looking at path and micro pictures, xrays, EKGs and maybe brushing up on high yield charts (OMM, nerves, bug-n-drug, etc).
Also, do as many questions as you can. There are a multitude of books an online resources. I did approximately 3000 questions. Each source was different and my averages ranged from 40% correct to 65%+. I have no idea what was accurate, but the questions I saw on the real COMLEX were NOTHING like the "practice" exam on the NBOME website. I used usmleasy.com and found it to be comparable to the real test. Kaplan Q bank were also fairly similar from what I saw.
Of the 750 questions on COMLEX I had 2 repeat questions from somewhere in my studying...possibly from an old COMLEX review or something. But the themes were the same.
I can tell you, it is a relief to get the test over with. After the first book I felt like crap, then once book 4 was done I didn't care...life was good at that point. We had it at a hotel...I recommend a shot of Jameson during the lunch break from the hotel bar to calm the nerves. 😉
