Mark or Knowledge?

Honestly, I think most students are in schools just to get a degree and they are studying just to get good marks. Its what people expect of them anyways. I mean isnt it the cycle? You go to school, get a degree, and work. Perhaps, enjoy and relax sometime somewhere in between. There are only few people who say they are in school because they want to gain knowledge. I think mostly they're the ones who already have gotten a degree that would give them a good paying job. Since they have already done that they can do what they really want. Thats just what I think anyway.
