    Overall Experience: I've been here for three years most of the club that you have to try out for the same people over and over again the only difference about them is the freshmen that are selected. There are some clubs that try to bring in as many new members as possible including the seniors or juniors sophomores and freshmen. The sports team coaches need to be improved work on personal skills they need to build up their program from the bottom up not just transferring a whole bunch of people. If they are unable to do so they need to be replaced especially if our sports team isn't winning.

    Teachers: Some teachers try there absolute best to go above and beyond to help the failing students. However not all of them truly care about the students, and often said that they were just there for a pay check. Instead of engaging all students in the class discussion that often just picked on the few brainiac.

    Food: In between classes I often go to the student store where they do have a variety of snacks available. During lunch they have these ladies working carts where even more snacks are available I don't often eat lunch because the lunch line to too long.

    Administration & Policies: The school dress code in my opinion is very stupid you're telling girls that we can't wear leggings because it distracts the boys like how is it our fault that they get distracted too easily. You're basically telling us that if something bad were to happen to us that it's everything is our fault you're teaching girls that it's okay to blame yourself instead of blaming males.

    Sports & Fitness: Many of the sports at my school are very political; I haven't made varsity water polo because I don't play at the correct club that my coach coaches at. They don't tend to build up their sports programs instead they have people who go to their certain club transfer in and promised them to have a spot on varsity as a freshman. Most of the players on varsity I've beaten before yet they still seem to have more playing time than I do.
