What people are saying

by a student
Monday, September 21, 2009

I spent most of my life struggling in school but whenever one of my friends attending a different school are working on their homework, I automatically feel smart. I feel this way because I look over their shoulder and notice what they're working on and it's never even close to what I'm learning. Even though some of my friends are in the same grade as me, their education is not as great. I used to think it was a pain having such strict teachers but I honestly love it because I get the education that some students only dream of. I've come to notice that Radnor has a strong staff that not only cares about a student's academic performance, but makes it clear that they want you to succeed. It isn't everyday that some students can wake up to that. The facilities alone make me realize how blessed I am to be part of such an elite high school. I don't know who reads these reviews, but if this is a parent who is looking for a school for their kids, don't hesitate to keep this as an option. I have just started my senior year and since the first day I walked the halls of Radnor High, I've seen nothing but improvement when I thought it couldn't get any better. Close Quote
