Hi swarup1981,
46 hours of study each week would be a LOT (especially if you plan to do that each week for the next 2 months) - and you have to be careful about not 'burning out' before Test Day. This is meant to say that you probably should not study that much, but it's ultimately up to you to keep track of how you're feeling and make smart choices about your own well-being. Based on everything that you’ve described, I think that you would find the EMPOWERgmat Total Score Booster to be quite helpful. Most of our clients complete that Study Plan in well under 2 months, so the time commitment should fit your schedule perfectly. 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,
