You can take a makeup quiz or exam with no penalty if:
If you don't have a good reason, or it isn't verifiable, or you weren't prompt in arranging to do the makeup, you can still take the makeup but there will be a penalty of 10% of your grade for each week day you are late in taking it. For example, if an exam was on a Monday and you take the makeup the following Wednesday, without having a good and verifiable reason why you couldn't do it Monday, and you get 75% on the makeup exam, your penalty is 75*0.2 = 15%, leaving you with a score of 60%.
You have a good and verifiable reason why you could not take the quiz or exam at the scheduled time.
You promptly inform me and arrange to do the makeup.
Makeup quizzes are done on paper, closed book, like an exam.
Quizzes and exams aren't given early. If you can't do a quiz or exam at the scheduled time you need to do a makeup later and accept the penalty.
