From scratch to ace GMAT

Strengths:

E-GMAT has tremendous amount of resources for every aspect of exam prep. I was at first astonished by the daunting amount of basic concept files that I have to finish before I dive into scholarium quizzes and mocks.
Before I got to know E-GMAT, I didn't have any thorough concept for how to approach every sections and questions.
However, following the entire curriculum for 2 month with patience, I finally made achievements at scholarium quizzes and started to interact with e-GMAT team from then.

Would make the product better:

Concept files, Scholarium quizzes, Cementing process, Sigma-X mocks and other possible materials are all necessary steps to ace GMAT.
Especially, Sigma-X mocks are very accurate indicator/predictor of your actual skills and scores.
And, if you want to improve your score in a short period of time(maybe to 1/3 than preparing for your own), you'd better follow the e-GMAT instructors' guidance as much as possible.

Before I met e-GMAT, my score was stuck in 660 until third attempt. I trusted my English skills, because I have usually achieved the highest scores at TOEIC/TOEFL reading comprehension.
After I started to study with e-GMAT curriculum, I finally realized that I totally misunderstood the GMAT exam and decided to revise my approach as e-GMAT curriculum says.
Also, there was a lot of support from e-GMAT professionals, from thorough plans to follow to timely response to all kind of inquiries.
Though it took longer period than the e-GMAT team suggested because I have a full-time job and have up to 2 hours a day to study, I eventually saw the achievements at mock tests.
Sigma X mocks : 680 -> 730 -> 720
Official mocks : 700 -> 760 -> 750 -> 720.
Though the scores are fluctuating because I could not maintain the rigor of study plan due to work, the e-GMAT team's support and feedback for every mocks I have taken gave me further insights for my faltering points and actions to be done in the near future.
So, even though I got 720 at my actual exam, I am pursuing for another exam with confidence.
For me, visualization for every passage and sentence is the key to all the skills that follow. This is the most important basic mindset when you address various questions.
Regardless of the difficulties of the questions, proper level of visualization and following pre-thinking will put you on the higher position than other test-takers.
e-GMAT will make this happen if you are with them, and the advertisements saying "600 to 750 in xx days.." are not lies. You too, can be the very person who made miracle.
