Actually I'm so sorry, but I did not study verbal-the only thing I did was to do all the exercices in the OG for sentence correction at least twice, because I'm not a native speaker and I thought it would be sad to lose points because my grammar isn't perfect.
But reading comp and crit. reas., every time I tried to apply strategies (kaplan offers strategies for each type of question), my score kept going down.
I think concentration is key here. It's the last hour of the exam and when you get to Q20 you think, only 20 questions and I get my score, and you start losing concentration. Well stay concentrated. You need to focus your entire body and mind on each individual question. There is no approximate answer on the GMAT verbal-4 answers will be wrong. If you pick an answer and have a doubt or if it seems imperfect, then you have the wrong answer. It's exactly like quant in a way, except because it's not numbers you can't verify your answers.
