Simulates test environment effectively and has great database of questions

I used TargetTestPrep for about one month as I approached my first GRE exam. I used those 30 days to do as many practice problems as possible and learn what I struggled with so I could do a bit of supplemental reading as well. I did probably 40 to 50 problems daily on their website and found their practice problems to be very detail-oriented, which is one of the most challenging things about the GRE quantitative section. Overall, it is a great way to prepare for the course. If you use this resource and do as many problems as possible, you will not encounter any surprises on the test and should be able to succeed. I ended up getting a 167 on the quantitative section and attribute much of that to their program.
