Must have tests

Overall test are great. I feel the non-adaptive part of the test a game changer for me as it keeps on giving me harder questions to improve my overall performance. My score range was 650 - 700 on these tests and I got 700+ on 2 free official mocks. Mocks can only help you if you revisit the test and learn from the mistakes.
One of the key aspects of the mock tests is the detailed and interactive post-mock analysis based on individual sections, topics as well as the difficulty level of the questions along with the historical data on how a candidate has been faring in these sections. The interface is also similar to the actual GMAT test which helps the candidate to avoid any adjustments on the test day.
