I have my GMAT in exactly a month from now. Overall, my performance is pretty good overall - scoring q50 - q51 and around v38 - v41. However, I would like to increase my verbal to v45+ (q51 - v45 is a killer). Is there -any- company or method that offers excellent training around this level? I am NOT looking for a method that starts at the basics, because I do not have the time and commitment to go over all of that again. I am only looking to consistently answer level 700+ questions correctly, especially in Sentence Correction.
I am hitting around 80% accuracy on level 700 CR / RC questions (at least, according to 'collection of level 700 questions' on GMATClub), but my SC is lacking behind.
Any company or method that will help me improve my score is appreciated. Prices are not a major decisive factor - quality is.
