The exams provided great basis. I highly recommend purchasing the tests and going through all questions in a timed environment. I used the test to help my exam, and currently I have improved my score from a 500 - 700 +. If you consistently use the software and book you will improve. highly recommend.
MGMAT CATs have questions of a higher level of difficulty when compared to the ones of other CATs available online for practice . I would strongly recommend to take CATs offered by others like veritas, gmat club to get a better understanding of where one stands.
Overall, Manhattan´s CATs are, have challenging questions and great explanations.
