The academic quality is GREAT! There are many teachers with different personalities, but all of them are wonderful teachers with their own unique style of teaching. There are many clubs, music classes, and sports you can participate in for extra curricular. The school is kept very clean and is kept in good shape by the security officers. I would recommend this school. It is modern and is in good shape overall.
