I was looking at combank and there are 2000+ questions. However, there are several categories that may not be high yield at all in the actual comlex, such as biochem. I was wondering what other categories do people find useless? I know bugs, drugs, omm, path is pretty big on comlex. What about peds, anatomy, behavioral, medical ethics or biostats? These make up about 500 of the questions on combank, just curious on how many of you have gone through it.
