What I didnt like about the questionnaire

I have seen a few things that could be changed in this questionnaire in order to improve the quality of the questions. I think that some of the questions dont have enough choices for the answers. Like with the question about if I have enjoyed my classes so far. There are only three answer choices: agree, disagree, and not sure. If you add other choices such as somewhat agree or somewhat disagree you can get a better idea of what people really think about their classes or better yet add in an essay portion for the questions so that these answers can be better explained. Some of the questions dont even have the right answers so some people wont be able to answer the questions. Like the question that asks what is your major, that question lists only a portion of the available majors in college.
