Notes on the Exam

• I graded the exam in the order A, C, B.
• We'll go over them in that order, too.

Problem A: Average

All of my comments can be found in the notes on the exam. We'll go over them in some detail.

Problem C: Fixing the Book Class

All of my comments can be found in the notes on the exam. We'll go over them in some detail.

Problem B: A Registration System

• Your answers on #2 were often fairly bad. However, I was fairly lenient in that grading since it was the last problem.
• A number of you neglected to include courses in the student record.
• I emphasized the fileds of the student class in grading this problem.

Notes on the Project

• I expect to see similar attention to detail in your work on the project.
