*If you missed a quiz due to an excused absence, you will need to come to the classroom to make it up.   It is in the Quiz binder at the front of the class.  Quizzes given in each unit must be made up by that unit's scheduled test date.  Take the quiz on your own half-sheet of lined paper, fill out a late-work-form, staple it to the quiz, and turn it into to LATE basket.  If you are making up a quiz due to a tardy, it will cost a punch on your slacker pass.
