PSYC 1000, Exam 3, April, 2008
To determine your current standing in the class, you should take your total points (posted in BlackBoard) and add up to thirty points (five points for each research participation credit earned). If that yields 270 or more, you have an A, 240 or more a B, 210 or more a C, 180 or more a D, below 180 an F.
Here are some statistics on the distribution of grades. In computing these statistics I have assumed that each student has earned three research participation credits (15 points).
