Assigning grades to fit some "optimal distribution" is misguided. We don't want to maximize the entropy of the grades in a particular course. It's not a very useful measure of a "good" set of grades....

Without trying to evade your question, it is extremely difficult to quantify the impact of different grading distributions. This makes it not possible to find an optimal solution. You state 2 goals...

Your question is really impossible to answer because you don't give us the measurable goals of your grading distributions. Some sort of Bell Curve (example #1)This is clearly flawed because it poses no...

I agree with other answers: there is little sense to change your grading paradigm a posteriori until you get some distribution.However, it can be useful to test your assumptions by formulating your...

The right distribution to use is the one that the students are used to.I would dispute your assumption that more entropy is always better than less.Lets imagine a student who typically receives a B...
