I surpassed by score goal, and only used TTP and practice tests as my study material. It has everything you need to be successful, and allows you to work at your pace. My first GMAT score was a 560 (a few years ago), I then improved to a 710, and through TTP was able to score a 715 and 88 quant on the GMAT focus after just 6 weeks on the course.

I cannot recommend this tool enough, it was a great decision for me.
