That was funny

Here is a list of the ways professors grade their final exams:

Dept Of Statistics:

All grades are plotted along the normal bell curve.

Dept Of Psychology:

Students are asked to blot ink in their exam books, close them and
turn them in. The professor opens the books and assigns the first
grade that comes to mind.

Dept Of History:

All students get the same grade they got last year.

Dept Of Theology:

Grade is determined by God.

Dept Of Philosophy:

What is a grade?

Law School:

Students are asked to defend their position of why they should receive
an A.

Dept Of Mathematics:

Grades are variable.

Dept Of Logic:

If and only if the student is present for the final and the student
has accumulated a passing grade then the student will receive an A
else the student will not receive an A.

Dept Of Computer Science:

Random number generator determines grade.

Dept of Music:

Each student must figure out his grade by listening to the instructor
play the corresponding note (+ and - would be sharp and flat
respectively).
