Hi soumyaranjandash87,
To start, unless you used each of the products that you 'tagged' in your title in its entirety, you should remove those tags from your post.
If it's really been over 2 years since you were regularly studying for the GMAT, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can download 2 for free from
www.mba.com (and they come with some additional practice materials). If you want to do a little studying first, so that you can refamiliarize yourself with the basic content and question types, then that's okay - but you shouldn't wait too long to take that initial CAT. That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 4 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
I'd like to know a bit more about your timeline and goals:
1) When are you planning to take the GMAT?
2) When are you planning to apply to Business School?
3) What specific Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
