The Geometry Final Exams are scored and in Skyward. Grades are not yet finalized as I have a small stack (pronounced "Mountain") of makeup quizzes, absent work and other things to enter. Overall the grades were good and I am proud of all my geometry students and the success they showed me on their exams.

I did want to take a moment and explain grade scales because I can with the data I have here:

The traditional scale, and the one used on this final is the standard 10% split for all grades. The exam was out of 75 points so the scale goes like this:

A: 75-68, B: 67-60, C: 59-52, D: 51-44, E: 44 and down

Now for one of the two classes, I won't say which, the mean score was a 64, median was 67, and there was a Standard Deviation of 15 points. So if we had used a Curve to figure the grades we'd have a different scale:

A: 75 B: 74 C: 73-59 D: 58-43 E: 43 and down

That means that to get an A you had to have landed right smack dab on a perfect paper. Why? Well remember that with a true Curve, the objective is to have the majority of your scores be considered "average" or a C. With this grade break down, because everyone did so well, it pushes that curve upwards and makes a B and an A harder to get. Also, remember that with a Curve you should have roughly the same number of A's (3 students out of 30) as you do E's (3 students out of 30).

Because grade curves are highly competative, I generally don't use them. They just put too much presure on students to do better than their peers rather than to do the best they can do.
