One reason for performing a course evaluation is that it allows you to make your voice heard regarding the course you have taken. You do this to improve the course for the benefit of future students. It is, however, not only for those that come after you: If the educational programme improves, so does its reputation, which means that your qualification becomes more attractive. So, make sure that you perform the evaluation for the sake of both future students and yourself!
