School Reviews
5 2/28/2012
I read another review of this school and it said that there are alot of potheads here.Nowadays there are going to be potheads at every high school. The main focus at this school is that my freshman daughter likes this school and the Teachers. She is eager to learn--isn't that what a good school should be about? The students know that if there is a problem, that they have someone to go to. Isn't this also what a good school should be? The courses that are offered are diversified, there is something for everyone to choose. I was reluctant at first to have my daughter go here from the reviews that I had read. However, I would rate this school as very good and the teachers and staff as excellent and caring for their students. Isn't this what a good school should be? I think so---I would highly recommend this school to any student wanting to go here. Every school is going to have students wanting to party instead of studying--it is up to the individual student to make up their minds what they want from their lives. Peer pressure is everywhere--this school is available to the students with any problems. I think this is what a good school should be-------Signed a parent of a freshman.
