Grossmont High School Reviews

By a Former Student on

It's a very good school. Pretty much all the teachers are nice, and the campus is kept clean. The counselors are also very helpful and do anything they can to help students keep track of their credits, and help them get prepared for college.

I don't see why we arn't able to use our cellphones. All the other schools are able  to use their phones, but were not allowed to. WE have the highest test scores and have proven that we would keep them up and you keep these students on lockdown. I switched schools at at my old school, we were able to use our phones but have them off durring class, and at this school... NOTHING.

I also feel that we as seniors should have an open campose. WE have worked hard up all the way to our senior year, and we should be rewarded with being able to leave durring lunch, and if students don't come back then they should be punished.

I know NONE of this is even going to be looked at, but i want you to know how the STUDENT body feels, not just one student.
