Great resource for practicing hard problems

The test questions are of very high-quality. Although many reviews can be found regarding the quantitative section, I also feel the verbal question collection is great. Any student aiming to score 650+ should subscribe to these tests. Moreover, the tests come with detailed explanations, in most cases, which help to look at the problems from different perspectives i.e. different ways to solve. The report generated from the practice is very detailed and is an excellent tool to gauze expertise and weaknesses in various areas; and manage limited study time in the most efficient manner. I would definitely recommend these tests to anybody aiming for an above-average GMAT score.
