Hi
Digvijay101The first step would be to take a free test(available on mba.com). Once you have
a preliminary score, the experts at this forum will be able to suggest a strategy.
To improve your verbal score, you could try the free trials of the various prep
companies, which you can find here on GMATClub.
You could check the reviews here:
https://gmatclub.com/reviews/gmat_courses?fl=menuSome additional books/course I would recommend are as follow
SC : Aristotle SC Grail/
e-GMAT SC(they don't offer the individual package, but you
could try talking to them. Worst case scenario - Take the verbal package, costs $199)
CR : Powerscore CR Bible - This book alone is enough to improve your CR skills
RC : Read this
post.
For Quant, you could use the
ULTIMATE GMAT QUANTITATIVE MEGATHREAD for concepts.
Would be happy answering any specific questions that you might have.
Hope this information helps you!
