When I was researching prep courses, I gleaned from the reviews on various websites that Target test Prep had a very comprehensive course with an extensive question bank. So I decided to go ahead with TTP because it seemed very reasonably priced for the vast resources they offered. I am a working professional so TTP being a self-paced course suited me perfectly where I could customize the daily study plan around my regular schedule. The daily study plan regularly scheduled review tests every few days which prevented me from forgetting the old lessons while progressing through the curriculum. The quant lessons were very effective because they were based on reliable and replicable techniques. The "must-knows" in each lesson helped summarize the main take-aways from each chapter without having to do it myself. The physical Active review sheets were very useful during the revision phase of my prep when I was sitting for Official Practice tests. The error log and data-driven analyzer built into the TTP module helped me improve my scores on the Mocks from a 89th percentile to consistently scoring above 90th percentile because I was able to easily understand my areas of strength and weakness and focus my prep on specific topics accordingly. I would highly recommend TTP to anyone who is starting out without a strong background in Quant/Verbal, it will help you learn everything you need for the GMAT from the ground up!
