Excellent school, very diverse, welcoming, open to ALL types of students, wide range of AP course offerings, very good sports teams Close Quote

Monday, November 2, 2009

This school spends most of its funding on art and remodeling instead of creating a smaller classroom environment. An average class size would be 35 students and up. There are too many harassments and misbehavior disrupting a school environment. The teaching quality of an average instructor is not that high. Close Quote
