Where should I put my study time?

Hi guys,

Great forum, very helpful. I am wondering if you can help me figure out what to study for more - Quant or Verbal?

I just took my first GMATPrep test and scored 720, 48Q and 41V. At first it looked to me like my Quant was stronger because of the higher raw score, but when I looked up the percentiles, it says 48Q is 83rd percentile and 41V is 92nd percentile. So does that mean my verbal is actually stronger? Which should I concentrate in to get the biggest bang for my time?

During the test, the math seemed quite difficult and I had to guess at the end whereas I finished the verbal with 15 minutes remaining. In quant, it was the concept mixtures that threw me for a loop, whereas in verbal I had a thoroughly bad time with RC, though got some SC wrong as well. So there are many things I can improve in, but I'm afraid to exhaust myself. Where would you recommend to focus?

Also, what are some strategies that people have successfully used for RC? My problem is over-analyzing the passage when answering questions and getting so bogged down with detail when reading that I tend to miss the important points.

Thanks for any tips!
