Exam Schedules
Midterm Exam: 28 October (Monday), In-class.
- Coverage: Chapters 1, 2, and 3.
- Total 8 questions. There will be one set of True/False questions (Please note that you get full credit if you are correct, no credit for no answer, and negative of the assigned score if your answer to this question is incorrect.), 3 questions which are identical or directly related to homework problems, and remaining 4 questions are from those discussed in class. This exam would gear toward giving advantages to those who were carefully following class discussions while keeping a good pace of doing homework.
- We still meet on 29 October (Tuesday) as scheduled for a regular class meeting.
Here are Problems and Solutions. The average was 46.93 and the maximum score achieved by a student was 95.
- If you think you did not get a score you deserve, you are welcome to dispute. Please do that no later than 18:00 of the day before your final exam day.
Final Exam: 16 December (Monday), In-class.
- Coverage: Chapters 1, 2, 3, 4, 5, and 6 (only those sections covered in class).
- Total 8 questions. The style and focus of the exam will be similar to the midterm exam. Chapters 1, 2, and 3 will be only indirectly covered in this exam to the extent that the exam assumes everything we studied together in this course. Exam problems will be mostly from those materials we studied after the midterm exam.
