Kalamazoo College has changed the way it calculates grade-point averages so that only an A, not an A- as has been the case, is worth a 4.0, MLive reported. An A- will be worth only 3.67. In another change, there will be separate vales for grades of B+, B and B- (3.33, 3.0 and 2.67, respectively). Previously, all three B grades were worth 3.0. Officials said that the college made the change not out of concerns about grade inflation, but to help students applying to graduate schools. Some graduate schools were recalculating Kalamazoo G.P.A.s because its prior system is not widely used.
