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 43. 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 originally 47 points possible on the Final, though a one-point part of a question — the one asking you to find one test case that would yield 100% node, edge, and path coverage — turned out not to have a correct answer, so it was thrown out. So, the scores here are reported out of 46 points possible. The average score was 35.25 (75.01%), with one perfect score of 46.

Here is an explanation of the various columns:

• The IDSuffix column contains the last four digits of your UCI ID# or Access ID#.
• The Phase1..Phase4 columns are your scores (out of 100) on each phase of the Course Project.
• The Phase3X column indicates the number of points of extra credit you earned on Phase 3 of the Course Project.
• The MT and Final columns contain your raw scores on the Midterm and Final Exam.
• The TotalPct column is your overall percentage in the class, not counting extra credit, figured by adding the weighted percentages of the project scores, Midterm, and Final Exam together, as described in the Course Reference.
• The TotalPctX column is your overall percentage in the class, including extra credit.

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.

It was a great pleasure to ride with you during my first Informatics 43 offering. Have a fantastic summer! I'll look forward to seeing many of you again soon.
