Exam

Midterm: The midterm on Nov 4 will cover materials up to Lecture note 9. However, materials in lecture notes 8 and 9 will be treated very lightly.
- The exam and the solutions. The score distribution and the full grading rubrics are available here.
- The review session is 3-5 PM on Nov 2, Sunday, in room PSB 114.
  - The audio recording and the photos of the blackboard are available for those of you who could not make it to the session.
- Last year’s midterm should be reviewed. It should be regarded as a practice exam for this year. (However, you can ignore problem 2.) (solutions included)
- Last year’s pre-exam can be reviewed as well. (solutions)
- There will not be any quiz on this Thursday (Oct 30), nor will there be any new homework given out on that day. A new homework will be posted on Nov 4 and will be due Nov 13.
