What people are saying

by a student
Thursday, January 10, 2013

I'm from the inside. I know what it's like. That school is one of the most classy, most persevering schools out there. Those who have met the staff, the students, and forgot about the ghetto floors and prison like structure, have always walked away wondering what was so different. And that's just it, one shouldn't be able to articulate exactly what is so different,only that it's the difference that counts against all of the cliche, boastful high schools around. There's a silver lining between boastful and prideful. And Centennial has definitely found it. Close Quote
