Hi NTS3,
There was a post on the "Everyone" page within the last month that said something like "Verbal Reasoning Help - for those who want to know." I never read the post, but it may be useful to you. I'm not sure what advice anyone can give you without knowing where you are having problems.
So, I guess the best thing to figure out is: 1) is it a timing issue (either going too fast or too slow) or 2) is it a comprehension issue (either getting too absorbed in one passage at the expense of others or that you just aren't "getting it" with some passages)? These are the things most people have to work through with VR, I think. If you are taking a prep course, get extra help from your VR instructor. If not, try getting the book "Reading Smart" by the Princeton Review. It teaches you how to read faster without compromising comprehension. It was helpful to me.
However, if you are planning on the August MCAT, the best thing to do is identify where you are having the problem(s) and then create a strategy to deal with it. Some people go through all the passages, knowing they will miss a few questions, while others sacrifice getting to all the passages for higher accuracy on the ones that they do read. Obviously, reading all of them with 100% accuracy is ideal, but for most of us in a timed test, we have to sacrifice one for the other. Try a few different approaches on practice tests and then pick a strategy and go with it. Good luck!
