Delcastle is a vocational high school so the education was not that well, nor were the sports nor were the people. Delcastle was meant to prepare students to go right into work so the colleges it prepared you for were limited with no AP classes and honestly if you're gonna go there then go with the idea that you wanna get right into work and not go to college.

I loved the opportunity since the day I stepped into , delcastle votech. Till now a senior, they really do set you up for success and for college. I'm 18 and already work as a medical assistant at Nemours children hospital!! I hope to be a RN one day, Delcastle was the best school I could ever go to.

There are three women working in there and they operate well below any poor level of effectiveness or efficiency. They are unpleasant and uncoordinated and apparently they don't get along wi...
