March 2013 Break Take Home Test

Answer each question and bubble in the correct answer on your scantron. This completed scantron is due on April 1st or whenever you return to school, whichever is first! The assignment is worth 100 points. A 20 point deduction will be taken for each day it is late. Be very careful with your scantron!! I’d even recommend answering the questions on a separate piece of paper first and then transferring to scantron when you are very sure of your answers. Questions begin on the next page…good luck!
