<p>drax12 - Your logic escapes me. That is a 1-1 mapping of scores, so it is identical in terms of detail, if that is as far as one takes it. For every score in the 0-100 scale, there is an equivalent score in the 4.0 scheme. As far as saying each scale point = 0.05 gpa points, that is just a matter of taking the 0-100 scale to an extra decimal point. Besides, in the real world it usually works the opposite way, as I have pointed out. Most teachers grade tests numerically (“I got a 92 on that test”) and then in the end take the average of all the tests (say a 87.3) and call that a B+, which is then recorded as a 3.33. You actually lose precision in this manner because an 86.5 might also be a B+, so the student that did a little better appears to be the same as the other, but also looks the same as the student that got an 89, which might also be called a B+. So I think you have it exactly backwards. BTW, I certainly always thought an 80 was the lowest B-, and a 70 the lowest C-, if you are doing + and -. But I am sure definitions vary, another problem with converting from the 0-100 scale to letter grades.</p>
<p>vossron - My objection was to your use of the word “official”. Maybe I am misinterpreting how you are using the word.</p>
