GreatSchools Rating
Parent Rating Average
I do not like this school because of certain teachers that don't teach well and make me not understand the subject. This school does not make me enjoy going to get my education. I think that they should also work harder to make this a more diverse and inclusive place. This school is not diverse in the slightest and does not feel inclusive to LGBTQ+ students or students of other races. This school also does not do anything about the misgendering of trans students at this school. It does not feel like a safe space for everyone.
