Saw another thank you 7sage and thought to write my own! I took my first diagnostic and was heartbroken considering my goals included top schools and I was concerned about taking on debt. I used this program for around 7 months before my test and getting my score back was one of the happiest moments I have felt in recent years. To think nothing is off limits because of this website still makes me tear up. So overall, I just want to thank the developers and the teachers for making such a great impact on so many peoples lives!
