Hi Swati,
First of all, I have to warn you that it takes a lot of work to do well on the GMAT. Even a 600 is better than most people do on the test. However, there are some things that can do that would give you a fighting chance. First, you should focus on the Sentence correction section for your verbal studying. I liked the Manhattan GMAT SC book. You need to read a SC book (perhaps several times) and then do hundreds of SC questions to build up your speed and accuracy. I say that you should focus on the SC section because it's easier to improve your grammar than you reading ability. You should read for at least 30 minutes every day though. I would use the Official guide reading comprehension and critical reasoning questions to practice. As for math- there is a ton of information to learn, but you may be better off mastering certain subject areas instead of having a mediocre handle of everything. Again, I think the Manhattan books would be useful here.

Hope that helps and good luck
Dan

Swati:

Daniel raises some good thoughts/suggestions. Less than a month -- whew! Is that a firm and hard deadline?

You need to come up with a prioritized list of where you want to focus -- by no means will you be able to cover 'everything' in 30 days. Plus, I'd recommend taking at least 2 if not 3 more practice exams before the big day.

Stacey's got a good article on what to do in the last 14 days -- https://www.beatthegmat.com/mba/2010/08/ ... -game-plan -- which is not exactly the situation you are in, but since I don't think there's been a ton of prep to-date in your case, this might be the right attitude/approach.

Can you share any details on how you did verbal/quant on the one exam you've taken?

Thanks!
