text: Divide by 25.\n\n(EDIT: OK, maybe I'm not too bright - DUH! Let me rethink this and I'll provide a "re-edit.")\n\n((RE-EDIT: OK, so let's assume you have the "90/80/70/60" scale:\n\n>=90 - A\n80-89.9999* - B\n70-79.9999* - C\n60-69.9999* - D\n<60 - F\n* - this could differ if you decide to round 89.5 up to 90 to eliminate decimal issues\n\nIn a perfect world, perhaps where there is a 100-point scale to separate the "90's" from the "98's," those who really kick butt would have a GPA more indicative of how they rank. As it is, with most 4-point scales, the "90's" have 4.0's just like the "98's," and that's not wholly fair. So, we'll say 100=4, 90=3, 80=2, 70=1, and 60=0. That would mean a more ideal 4-point scale (based on converting a 100-point scale) could result in the following equation:\n\nGPA(4) = ([GPA(100) - 60]/10) + some factor to account for any rounding or where you set the grade boundaries (i.e. Is 60 really going to get 0 grade points?)\n\nWhat do you think? Sorry for the simplistic answer I first provided - I obviously hadn't thought it through.))
