As a college student now, I look back at my high school years and wish I had an app like this to improve my scores. Even though I am going to a great school now, improving my SAT scores would have settled my mind a little more. It is just like other SAT books but cheaper and you can practice it anywhere, even while you are standing in line! I would recommend this to anyone who is serious about their college application process and really wants to improve their scores!
