it's my composition. help me plz

0 Just a few days ago, about 7,000 university students rallied in downtown Seoul, urging the government to nullify universities' decision to raise tuition fees. These days the tuition has been so drastically going up that many students and their parents have had difficulty in paying it. Our university, GSNU, is also no exception in this situation. So I agree that the tuition fee is very expensive and should go down. However, observing our campus, especially our library, I feel something is wrong. It is actually not that difficult to find people who always complain the tuition is expensive, wasting their valuable time. In my opinion, If we are worried about the tuition fee, what we have to do is not only to protest against rising tuition fees but also to be able to make the use of our university properly. But, as far as I know, we don't. To start with, although our university library is open from morning till night, not so many students use it. For instance, A few days ago, I was reading a book in the main library at about 8 pm, which close at 9:00 pm. But there were few students. Especially, the reading room in the main library is open 24 hours but many seats remain unoccupied. Actually, not student but their books occupy many seats because they put them on the seat and just go out. This is why I think what we say and what we behave seem to be contradictory. The library is run by our money. If we are worried about how expensive the tuition fee is, why don't we use it? --------- it's not yet finished. but, give me any advice plz. grammar, expression, somthing like that plz !! 0-
