GMAT whiz course review

I am a marine engineer by profession and around Feb I decided to attempt for GMAT this year. The major concern for my journey was poor internet connection and availability of time.
I begun my journey with the GMAT official guide, from which I got a certain idea about the exam and the type of questions. Verbal section sentence correction was the biggest challenge that I faced. To optimise the output from the time I put in to study, I was looking for the best alternatives. I took trials of EGMAT and GMAT whiz.
During the short trial I noticed that EGMAT required better internet connectivity to stream over GMAT whiz which could run even with slower internet. Another main advantage and the major reason for which I picked GMAT whiz was it's time oriented personalised study plan.
I could not go through with studying onboard as the internet connectivity was totally lost due to technical reasons but when I returned I went ahead with the 2 months plan.
I had around two months of leave in which I had to study and appear for my GMAT.
My journey started around mid March, when I started studying full time.

The best thing that happened to me was the personalised plan and the diagnostic quizzes of GMAT whiz. The diagnostic quizzes helped me by allowing me to delete those areas of study which I was already good at and thus saving time.
I was studying full time and hence was able to complete my course within a month. Another good feature was the score predictor which kept me on track by suggesting an accurate score range for most of my journey.
The verbal section was excellent for SC, CR was good as well. For me personally I think due to scarcity of time, I could not follow the GMATwhiz methods in CR and RC. But the practice after the course on GMAT whiz quizzes and GMAT club helped me build up that over time. G
Quant section was excellent as well, the trap questions kept me under check at all times. Around 10-12(4*3) practice questions after every topic helped me boost my confidence to tackle the variety of questions possible from each topic.

Upon completion of course I attempted for my first mock. That's when I realised that even though my accuracy was good, my speed was too slow for the test.
I had my first call with Satyam then and he suggested me to follow the method to solve the X number of questions of Y type within Z minutes while trying to maintain the accuracy.
Hence forth I practiced with this approach, appeared for other GMAT whiz mocks and discussed with him after every attempt. He guided me during the process and kept me on track.
I appeared for two official practice tests before appearing for my final GMAT exam. Satyam helped me immensely through the entire process, even accommodated unplanned zoom calls whenever slots were unavailable.
I used only GMATwhiz as my study guide for my entire journey and GMAT whiz mocks and GMAT club tests for practice. I used GMAT whiz and official Practice tests for mocks.
I appeared for my exam around 10th May and could score 710.
I would definitely suggest anyone who is not getting much time to plan or arrange their study time/material, to use GMATwhiz for their GMAT prep. It will optimise the efficiency of their study efforts.
