Method

  1. Your composite is each part's share of its maximum times College Board's published weight for that part, added up out of 100.
  2. Cut points are College Board's released 2013 AP Biology scoring worksheet, turned into a share of the worksheet's maximum: 78% for a 5, 62% for a 4 and 45% for a 3.
  3. Your score is the highest score whose cut point your composite reaches. The line under it is the fewest extra marks on one part that would reach the next score.
