Seems to me that my school has some unusual test policies - or at least unusual in comparison to any other courses I've ever taken. What do you think?
Students take individual tests. Following the individual tests, the students are assigned random groups of five members and take a quiz as a team. If the team score is an A, 2 points are added to the student's individual test score (1 point for B).
Faculty analysis of tests: On an exam if 90% or higher of the students answer correctly (or 70% or higher answer incorrectly), a question is reviewed, may be found "inadequate" by the faculty and thrown out.
