My 2 year journey to a 740

The e-gmat course really helped me with SC and CR sections in verbal. Prior to taking this course I had the pick the right answer approach, however e-gmat helped me develop the eliminate the wrong answer choices approach. The concept file and scholarium provides you a good set of practice questions and are for sure GMAT level questions.
Also the e-gmat planner is a very healthy tool to put a timeline to your preparations provided you stick to it no matter what. Be honest about the time you can dedicate on a daily basis and it would provide you a timeline according to which you can plan your GMAT. Make sure you have sufficient time remaining post the e-gmat course completion to write the official mock tests available on mba.com as they help you access where you stand.
