Double800 was a great experience for our school. We contracted with Micah (after interviewing Double800, Kaplan & Princeton Review) to teach a group of our juniors and seniors -- and the results were amazing! The increase in SAT scores for seniors was as much as 260 points; and the increase in PSAT scores for juniors qualified several as National Merit Scholars. Even better was the increase in confidence we saw. Students who took the class broadened their college horizons, and we have seen more applications to selective colleges and universities than we at first expected. 

Thank you, Micah! We will definitely continue to recommend you to our students.
