I'm in the same boat.
My experience with the GMAT tells me that I should be riding the short yellow bus when it comes to Verbal.
My breakdown: 48Q, 28V.
The good thing is that quant isn't bad but I know I can do better (i.e. 51).
Verbal--I took 3 months to relax and re-assess my approach. In the past I would do as many problems as I could to see if I could find a pattern, then focus on those questions only. For me, this is the wrong approach.
Now, I focus on a packet of SC questions and drill down each question so that I understand what is being tested.
Know why each choice should be eliminated: awkward and wordy, incorrect modifier, subject - verb agreement, etc.
When I first read the given statement I try to identify the type of question right away. Modifier? Find the modifying clause and find the correct noun it modifies. Comparison? Make sure you're comparing nouns to nouns. Is there a list? Check to see that everything is paralell. Idioms? You just gotta know these (flash cards helps).
I have taken a very systematic approach to verbal now. I always ask myself, "what are they testing me on for this question?"
For CR it's incredibly helpful to use this approach. I summarize Premise 1, Premise 2, What the assumption is (in my own words), and the Conclusion. Try to find answers that have the same evidence in the given premises. Many times, you can eliminate choices b/c many are out of scope (i.e. they bring in new information not discussed in the original passage).
For SC, identify the type of problem they are asking. You can usually get it down to 2 or 3 choices right away. Once you do, you need to compare the differences and identify the common tricks GMAT folks like to test on (i.e. verb tense, paralellsim, idioms, pronoun error, etc.). Once you get the hang of it, you'll notice that many questions follow a similar formula.
For RC, i'm still working on this. I found the approach is to read the passage as if you're editing your own AWA. Read the intro paragraph to get a feel for the thesis of the passage. Then once you have an idea what the author is trying to communicate, you can identify if paragraph 2 supports his conclusion, weakens an opposing view, etc.
Hope that helps.
