Williams College uses a 12 point system that gives you credit on your transcript for an A+.This is how it works:Grade Value Assigned A+ 12A 11A- 10B+ 9B 8B- 7C+ 6C 5C- 4D+ 3D 2D- 1F 0To convert to a 4.0 system, you just divide by 3.It is short and sweet and should be adopted.Sincerely,Colin McNaull
