Best Prep Materials - hands down!

I am someone who always struggles to achieve great scores on quant due to lack of confidence, simple mistakes, and gaps in my fundamental math knowledge. Before using TTP I was going through Magoosh (watched all the review videos and did practically all of the practice problems) and was still only scoring in the 156-158 range on quant. After taking TTP I got a 165 and felt I could have gotten 168+ with just a little more concentration. The reason TTP is so excellent is because of how structured the materials are - they are really designed based on the psychology of learning. Progressing from easy to medium to hard questions in each unit is strategically designed with the easy questions repeatedly drilling you on the fundamental properties and principals so that by the time you reach the hard questions they are second hand nature. Because Magoosh was less structured, it was harder to identify where my mistakes in each unit were. Also, I found the review content much more in depth with TTP (and I preferred the written format to Magoosh's video format also). I will be switching to GMAT prep now and plan on using TTP.
