If I were you, I would reschedule my GMAT appointment and not rush to take my next GMAT.
I would spend time analyzing what went wrong and then work hard on each of these issues for a couple of months.
What was your breakup between quants and verbals?
On verbals, I would suggest you take the
e-GMAT course and enroll for it. It's relatively cheap and the instructors would be able to guide you during your verbal preps. It's tailor made for Indians.
Also, go through, re-read the
MGMAT SC book cover to cover and internalize the rules.
Go through the Brutal SC, CR documents on GMATClub - and also the verbal notes by whiplash, Gayathri, spidey etc - all are free downloads here.
On quants, I would suggest you go through the GMATClub Free Online Book and the various discussion threads on quant here - please, please review each question you got wrong and understand them.
Once you have studied thoroughly for a month, start taking tests again:
Take the GMATPrep practice tests at least twice.
Other than the
MGMAT tests, I would suggest you take the free Kaplan, Veritas, Knewton, PlatinumGMAT free tests as well.
Do let me know if you have questions.
But my advice would be: Please don't rush to take the GMAT again until you have realized and worked on what your problems were the first time around.
