I started preparing for GMAT in Feb'22 with the Official Guide. It was very confusing because I was feeling direction less and my preparation was completely disorganized. I started looking for free tutorials on YouTube and then I came upon a video of GMATWhiz. I signed up for free course and within an hour, I paid the fee and took the subscription.
Their course structure is very streamlined, thorough and explanations are very clear.
For Quant section, it took me around 3 months to finish the course, I used to study for around 20-22 hours a week. They have difficulty level marked for each question which is extremely helpful to make the judgement. Probability and Permutations & Combinations have always been my weakest part, GMATWhiz helped me a lot to improve. They have a huge question bank for Quant, all difficulty levels.
For Verbal section, they have an excellent course, I went through the Verbal course two times, first time at normal speed and second time at 1.5X speed. Going through the course second time made me appreciate the concepts and techniques a lot.
My mentor was Satyam Gupta, he knew that I was facing issues in Verbal, he guided me to focus on solving the question and not pay much attention to the timings. I did that and my accuracy increased. He also provided me with some study materials outside of what is available on their website. Not paying attention to timing created problem for me in the first two mocks and I was left with hardly 1 min per question for the last 8-10 questions. In the final stages Satyam guided to improve my timing and within a week I was able to give enough time to each question.
This is my first attempt at GMAT and I got 690 (Q48 V35) and this is the exact score (650-690) GMATWhiz predicted based on my performance during the course. I am very thankful to GMATWhiz team.
