I am a student of Seneca Highschool and have been for three years.
I wouldn't recomend this school to anyone if they had the option to pick their own school.
The lack of depth in the schools programs makes thing bland learning wise. The school is based upon sports, not education. There is absolutely no organization. If I could go to a different school, I would. None of the classes are a challenge. I don't find myself being pushed to learn anything new. The rules are quite bias and illogical. A very large portion of the teachers are coaches that lack experience as a teacher. I find the only reason they are only teachers is beacuse they want to be a coach.
