To answer some of the above questions,
-I did find PharmCards in my bookstore. As I mentioned, some say they're "out of date," so they may be difficult to find. I think they're only out of date insofar as they don't include some of the newer classes of drugs--for example, the bisphosphonates, some of the antibody drugs (abciximab, etc), and some others that I can't recall off the top of my head. For these newer classes I just went to the section at the end of Lippincott pharm and made up my own cards.
-I was intimidated by the micro on the exam, but when I took the actual test, I was surprised at how little there was on it. Definitely know your gram positive/gram negative schemes (i.e., what is optochin sensitive, what does gamma hemolysis), but I wouldn't worry too much about it. Granted, each test is different, but many of my classmates also said micro was not tested too extensively.
-As far as being scared about pharm, I was, too. My school teaches some pharmacology, but not as a separate course (we have an organ systems-based curriculum). My advice to an incoming MSII is to review the major classes (or learn them for the first time) as you go through pathophysiology (Robbins). This was very helpful to me, and I found that I remembered a lot more than I thought I would when I got to the boards. And be sure to learn the adrenergic and parasympathetic drugs--a lot of these showed up on my test. Also, know the major side effects of major drugs...there was a lot of this on my test, too (it was something I wished I knew better!!!)
-Finally, take my advice with a grain of salt. I haven't received my scores back yet!
(although I was scoring between 70-85% on Qbank, if that helps).
Good luck!
