Final Review Quizzes
There are 10 weeks left of school. At the beginning of every week you will be handed a
quiz paper with 5 practice final questions. They are due the Friday of that week. IF YOUR
CLASS DROPS ON A FRIDAY, THE ASSIGNMENT WILL BE DUE ON THE THURSDAY.
Each quiz will be worth 10 points, for a total of 100 points for the 4th quarter. This assignment is
mean to help you; however failing to complete the quiz each week will give you a zero on a test
for the 4th quarter.
