Do prep school students have an automatic advantage?
No. Every student is looked at within the context of the school he or she is coming from. Some prep schools are stronger than others and some public high schools are stronger than others. No matter what school you attend, you need to be challenging yourself and taking full advantage of the opportunities. If your school is not challenging you, a prep school might be a good option for you, but more so you are not bored than for the promise of a particular college.
