Mea culpa (Forgive me)

In my haste to tally your scores, I failed to calculate them correctly. If you got all fours and fives, your score is correct. If you received any threes or twos, I owe you points.
Here's why: on a five-point scale, 5= A, 4= B, 3 = C, 2 = D and 1 = F.
But 70% of 5 = 3.5, not 3 and 60% of 5 = 3, not 2.

For most people, it's not a big difference, only a couple of points, but every point counts. For a few people it's more, a whole grade difference.

Feel free to calculate your scores yourself and bring them to me on Monday and I will correct your score in engrade. Or we can sit down together and calculate it.

I'm sorry for any distress this has caused you and I apologize for my mathematical ineptitude.
