Good course but Not so personalised

The e-GMAT, popular for their reviews, ratings can get anyone's attention.

I used this course for 6 months but couldn't score more than 620 (V-25).

Positive: They cover SC to the depths. Once I remembered all the rules, exceptions, figuring out any SC error was easy. pre-thinking was good technique.

Negative: I felt bad with their responses as well. Found them little arrogant in dealing with my problems. Sometimes things can't be explained on e-mails, they should learn this. When thinking of course, I was able to connect with them on video call but when I was stuck with same score, there was no one.
RC is not well designed. GMATNinja's video are far better than the RC part of the course.

Overall, it may work for someone or may not but I wouldn't recommend anyone to blindly get trapped in ratings etc game. Do speak to fellow students and figure out.
Applies to all other courses out there.
