I wrote my gmat test month ago and received 640 (Q49, V28) but I had a temperature day before the test and felt bad on test day. After completing quant I knew that I wrote not bad, but on Verbal I totally exhausted and last half hour of test was a nightmare. I'm going to schedule my following test on 29 Dec, currently my Manhattan scores are 670-680 range with Q47-49 V33-36. Did someone with such scores made jump to 700 on actual test? My only weakness is RC since I'm not a native speaker. When Analyzing I found that from 41 Verbal questions 80-90% question distribution is normal (14 from SC, 14 from CR and 13 from RC), I have also found that making 12 normally distributed mistakes (4 in SC, 4 in CR and 4 in reading) means around 40+ score than 12 not normally distributed mistakes (7 in SC, 4 in RC and 1 in CR). So I want to balance my RC score in order to make 20-30 point increase in overall score. If someone can write useful tips on how can I improve RC in 10 days, I'll be very thankful.
