I would recommend Target Prep to anyone looking to confidently test on the GMAT. I work in PE and had pretty limited time to study. I found Target Test Prep to be very efficient at teaching the necessary materials and testing my knowledge. I am someone that really likes to be secure that I am going into a test prepared, TTP has a number of reviews and tests for all the materials covered, and really embraces time-based reviews that locks in your knowledge. I spent 3 months preparing, spending approximately 20 hours a week studying on average. I wasn't able to complete the entire test sets, but felt really strong prior to the test and the results followed.
