Your Quant score is very good and you should be pleased with that. Sorry to hear that Verbal wasn't so strong. I just took the GMAt and scored a 570 and I was very disappointed with Verbal as well. I thought I finished Verbal with a strong score, but was shocked when I saw my final result. It was a 30, but should have been much higher. Most schools will want to see at least a 35 in verbal (which is 75%).
Strangely enough, I would look at Sentence Correction. It is not as easy as it looks and the test maker really screws with the differences between answer choices. You think that when you see the correct idiom that you found the right answer choice. I think they really get test takers to take the bait on SC.
Just some thoughts...since you do well on Quant and SC is somewhat formulatic, I would try to beef-up on the SC. You should probably pick it up quickly.
