Hi matisch,
Based on the time that you have remaining before your scheduled GMAT, you have to make some significant changes (in a short period of time) to how you deal with the Verbal section to hit your score goals. If you have the flexibility to push your Test Date back a bit (even if it's just a few weeks to a month), then that extra time would be quite useful.
If you're going to stick with your current Test Date, then I think that you would find the EMPOWERgmat Verbal Score Booster to be quite helpful. Most of our clients finish that Study Plan in under a month, so it would fit your schedule perfectly. During that time, you'll also be able to access any of the Quant resources that interest you. If you can push your Test Date back, then I would suggest the EMPOWERgmat Total Score Booster. Most of our clients complete that Study Plan in under 2 months, so the time commitment wouldn't be that bad. We have a variety of free resources on our site (
www.empowergmat.com), so you can 'test out' the Course before setting up an account.
If you have any additional questions, then you can feel free to contact me directly.
GMAT assassins aren't born, they're made,
