Informatics 45 Spring 2010
Final Course Grades


Explanation (please read this first!)

Please spend a couple of minutes reading this section. It will answer many of the questions that you may have about the grading process, and will save you a lot of upset waiting for a response to an email question.

Here are the final grades for Informatics 45. By University regulations, at this stage, the cutpoints and the grades are non-negotiable, unnless we made a clerical error, such as recording a score incorrectly. (Seriously! This means you! Almost every quarter, I get at least one email that begin with a phrase like "I know you said that the cutpoints are non-negotiable, but...") We also can no longer accept new regrade requests on the projects.

There were 52 points possible on the Final. The average score was 48.78 (93.80%), with many perfect scores. Average project scores were also quite high and a fairly high proportion of A and A- grades were seen this time around.

Here is an explanation of the various columns:

There are a few words to be said about the selection of cutpoints. People are cutpoints; whole-numbered percentages are not. That means that the cutpoint for a particular grade is simply the lowest-scoring person who received that grade. For the sake of argument, if you received a percentage of 54.99% in the class, and someone who received a 55.52% received a higher grade than you (with no person in between), you didn't miss the cutpoint by 0.01%; you missed it by 0.53% — a substantial margin.

I enjoyed working with you all this quarter and hope to see you again sometime down the road.
