This place was the biggest waste of our money. The instructors didn't know what they were doing, and the material had a 1995 date on them. The class was so awful that my son's friends soon stopped attending, even though there was no refund. My son who has a 4.3 GPA and scored 780 and 800 on his SAT Subject Tests only improved 20 points. Don't waste your money on these guys.
