Hi
Anmolgupta824,
I would recommend you to take a GMATPrep Test immediately
to understand exactly where you stand. After that as you have
eGmat for SC scoring around 70-80% should not be such a
problem provided you have completed their SC module diligently.
Everyday, you should spend around 2 hours building up some
concept(eg. Subject Verb Agreement, Modifier etc) and practice
questions afterwards and see if there is improvement. Make
notes in places you are making mistakes in and go over them
several times before the exam.
For CR and RC, do extensive practice and make an
error log.
Keep reviewing both your
error log and the concept notes which
you make till around 10 days before the exam.
Take a GMATPrep(around 8-9 days before the actual exam date)
and then take a call whether you need to postpone the exam or not.
P.S the GMAT cannot be postponed(without paying the entire amount)
once there are only 7 days left for your test. If you postpone before
7 days, you will need to pay only 50$ as rescheduling fee.
Hope that helps you!
