Students may avoid math and science courses . University-level math and science courses have the reputation of being ones in which even good students can get low grades. Higher education becomes education lite . When instructors are discouraged from teaching challenging courses and students gravitate toward less demanding, high-grading courses, there will necessarily be a reduction both of the number of demanding courses available and of the enrollments of such courses that survive. These trends can be described as a 'dumbing down' of higher education or as the evolution of higher education 'lite'.

If gradually increasing grades went together with gradually increasing educational content, the upward movement of grades might be taken as a positive sign. Despite having some problems, student ratings have two very attractive features. First, they are easy to administer. Second, they provide a simple numerical index.
