What do students buy when they pay tuition?
Marizza181 [45]

Answer:

the right to attend classes at a school

Explanation:

This question seeks to address why we go to school. We go to school to study and get certificates of qualification. To study, we have to pay tuition fees. Tuition fees constituent fifty percent of a school’s income, and without it, you will not be able to get into a classroom in the first place. It covers almost 70% of what the student does in school and this to study in a class. It pays for all academics and research, the library, teaching support, and many more. A place to live at a school and transportation expenses are probably not included in tuition fees. These are other expenses that a student requires to survive.
