Your constant need for extensions on homework, quizzes, and exams has become a thorn in my side, and will cause me to make major changes in my syllabus next semester.   There will be no more extensions, for any reason.

Okay, I really won’t be that harsh.   But there will be a definite “you get a week” rule.   No exceptions

I will get your grades entered in the gradebook when I get around to it.   Get off my back about it.
