Not every year is different, just in the last year of college. Under normal circumstances, the tuition fees for freshmen to juniors are the same, but the tuition fees for seniors will be cheaper than before, because in the senior year, every student needs to practice, and the number of times he lives in the dormitory is very small, and the book fees will also change. There are few courses in senior year, and too many new books can't go out, which will affect the final tuition of senior year. At the graduation stage, the accommodation and fees will be refunded to the students, so the college tuition is different every year, only at the university.
