Great Practice for Quant

These tests are perfect tool to test your score. Tests contain mix types of questions from all the areas. Question pool contains lot of question for us to practice. The emphasis is on the quality of questions and not on the quantity. One can check his/her performance in detail, weak areas are highlighted and one can choose the questions they have got wrong in the test and create their own quiz of those questions. This helps in focusing on weak areas. You can bookmark the questions and have a separate set of all the bookmarked questions.
Explanations include different perspectives and I guess that is the most valuable thing for the preparation tests.
Verbal Section need little bit refining as questions , while 700+ type are good, need to be varied as compared to the actual GMAT.
