Наверное так: Why are you so stupid?
There are a lot of disadvantages of staying at school you are still treated like a kid, the teachers know your history and you don't get other life experience.I stayed in because it was an easy choice to do and didn't seem as frightening as going to college. I soon understood that people who had gone to college were doing more interesting things, generally had better choice of subjects and were treated as grown-ups. In the end I left school and entered the college. The sixth-form college provided an excellent atmosphere and good preparation for university. I took it seriously and worked hard
