Exams/Grades/Evaluation

Exams are reasonable in length and difficulty.
Adequate time is allowed for exams.
Exams cover material on which I expect to be tested.
Grades are assigned fairly and impartially.
The grading system was clearly explained.
Exams are announced ahead of time and are held as scheduled.
I understand the methods of evaluation used to grade my work.
My instructor returns papers/exams quickly enough to benefit me.
