This is a quiz that has 4 different versions, all the same format. I give out the 4 quizzes in a given class period to curb the temptation to cheat. The forms are distinguished with an: A, B, C, D.
I do not point this out to my students when I distribute them. The only section that is the same is the Listening.
There are 3 sections and a bonus. The grade can be calculated out of 15 plus 8 possible bonus points. I would calculate it 13/15 = 87% +6 bonus = 93%. I count each bonus as 1% point. For the students that ask, each blank is worth ~7 points when rounded.
