Extra Credit Points:
 AD Geometry - For every question correct
  on the DA you will receive one major
  grade extra credit point!
 Pre-AP Geometry – For every question you
  get correct you will receive half a major
  grade extra credit point (rounded up). If
  you get all 17 correct you will get 9 points
  added to a major grade that will benefit
  you the most.
