E-GMAT shines with a good platform and student support

Strengths:

- Good student support
- Good platform that is bug-free and has no lag
- Plenty of questions and varied levels of difficulty

Would make the product better:

- quant section is harder than official practice; can be discouraging
- mock test results are similar but not very close to the official practice test results

They have extensive practice on offer for students with their scholaranium section containing a large number of practice questions from verbal, quant and DI.
The learning is methodical (if only a bit too long) and covers all the fundamentals for achieving a good score.
Their platform is very good, with a responsive interface and 0 lag. While the official gmac platform is a mess, especially when used from two different devices.
The e-gmat staff was really helpful and was considerate when I faced certain personal challenges.

The quantitative section is quite hard in comparison to the official material from gmac. All the this pushes students to do better in this section, it can often be discouraging as well.
I am not quite sure is their mock tests are adaptive in nature but there was some difference with their mock exam scores and official gmac mock exam scores. (E-gmat percentile was lower than offical test, and the actual score was in line with official practice test scores)

Overall, a good product and I would strongly recommend it to any gmat test taker who is just starting out.
