Well Structured and Organized

I used Target Test Prep as my primary resource to study for the quantitive section of the GMAT and found it extremely useful.

Prior to TTP I was struggling to structure and pace my GMAT studying. After reading the reviews for TTP I tried it and have no regrets. The course is intuitive and offers a wealth of realistic practice problems to learn and review the concepts from the lessons. Some of the questions can be repetitive (especially in the later, more difficult tests), but they do a good job of reinforcing the concepts that the lessons highlight.

I did not use TTP for verbal so I cannot comment on that portion of the course.
