Perfect Quant!!

TargetTestPrep is really a great course and helped me get a perfect Quant score and a great GMAT score overall: 760 (Q51,V42). A 100 point improvement over my already decent cold score of 660.

Pro's:
- extremely detailed quant lessons and lots of quality practice questions (about 3.5k quant and 1k verbal)
- fixed study plan that you simply have to follow and that will cover every topic
- really detailed SC lessons, which will make you familiar with all grammar concepts needed
- nice and clean design
- completly digital course, with automatic error log and performance evaluation

Con's:
- you will need quite some time to finish the course in its entirety (i needed about 250 hours, but you could very well need even more time)
- CR lessons are good, however i don't think you need to finish every single CR lesson (focusing on the crucial topics is probably sufficient)

All in all a really nice course, all the positive reviews exist for a good reason :)
