Hi Abhishek,
With your score goal, you're going to need to focus on a consistent set of of Tactics - and that training will likely be a bit 'slow-going' at first (since you have to learn to think about the Verbal section in a new way). Remember that the Verbal section of the GMAT is predictable - so you can learn to take advantage of the patterns that the Verbal section is built around. Given the work that you've done so far, 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, but you should NOT try to 'rush' through that Study Plan (you need to build up specific skills before you worry about speed). During that time, you'll also be able to access any of the Quant resources that interest you. 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,
Rich
