Btw Bhumika you are no. 1 in starting posts without searching anything. And your questions & comments are also like a min. to min. daily update of what are you doing at ur home or wherever u are. I would suggest you carry on with your method and rather give us a second to second update. Atleast anyone of us would be able to write a biography for You. "How Bhumika prepared for GMAT got success and got life." Overall I appreciate ur daily contribution. Hope many others would be appreciating you for the same.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
