Your sister is a vocational high school student, right? Can enter the top 80 of Ningda. My classmate is like this. She studied for an undergraduate diploma, that is, the diploma of Ningbo University, but she is a teacher, so she can be a teacher in the future. Not bad! But if you study, you are not in Ningda, but in a college in the higher education park, and in a school with some junior college students. Of course, there will be several courses specially for you undergraduates. I am in the same school and different classes with junior college students. You can ask me if you don't understand anything.
