When I first encountered Scientology I'd already flunked one grade of school, was doing poorly in school with maybe a C- or D+ average and was frequently sick, missing maybe one day of school average. As a result of some auditing (Scientology counseling) and studying the philosophy of Scientology, I quit being sick, haven't missed one day of school or work since then because of illness. My school grades steadily improved to the point where on my state wide senior exam I got the highest score they'd ever had at the high school.
