I did this two years ago, it was fantastic. My class had two guys in their mid 20's (I was one of them) and about four high school aged participants. The methods taught in the class were very rigorous and effective. I felt like me and the other guy in his 20's took it more seriously and got more out of it than most of the high school students. Many of the graduate students staffing the clinic said that it was the funnest aspect of there graduate program.
