Relatively a decent school. There are several teachers who act very weird towards the students and some teachers do not provide any help. I had a math teacher and a global politics teachers who would never help out with my work and would make some racial comments about my ethnicity. Overall, handful of teachers are very helpful yet I really hoped for a better teacher and student.
