Midterm Test. There will be an in-class midterm test on Wednesday, October 21. It will be held at Exam Centre, room 300 (255 McCaul St). The midterm will cover the first two chapters of Folland. No aides are allowed for this test.
Recommended preparation (do not turn in): all homework problems and the following problems from Folland: 1.1, 1.8, 1.10, 1.17, 1.20, 1.23, 1.29, 1.30, 1.31, 1.32, 1.33, 2.2, 2.9, 2.14, 2.16, 2.25, 2.29, 2.37, 2.48, 2.56.

Final exam. The final exam will be held on December 11, 10am - 1pm, at SF1105. You will be allowed to use one one-sided letter-sized page of notes. Textbooks or calculators are not allowed for this exam.
Recommended preparation (do not turn in): all homework and midterm preparation problems, the following problems from Folland: 3.5, 3.15, 3.20, 3.23, 3.26, 3.35, 3.42, 5.4, 5.12, 5.18, 5.24, 5.26, 5.37, 5.42, 5.51, 5.66, 6.15, 6.19, 6.21; and the following exercises from Stein-Shakarchi: 7.5, 7.8, 7.10.

Grading. Grades will be based on eight homework assignments (5% each), Midterm test (20%), and Final exam (40%). I will also occasionally assign bonus problems.

Late work. Extensions for homework deadlines will be considered only for medical reasons. Late assignments will lose 20% per day. Submission on the day the homework is due but after the tutorial is considered to be one day late. Special consideration for late assignments or missed exams must be submitted via e-mail within a week of the original due date. There will be no make-up midterm tests or final. Justifiable absences must be declared on ROSI, undocumented absences will result in zero credit.


Academic Integrity.
Honesty and fairness are fundamental to the University of Toronto’s mission. Plagiarism is a form of academic fraud and is treated
very seriously. The work that you submit must be your own and cannot contain anyone elses work or ideas without proper
attribution. You are expected to read the handout How not to plagiarize (http://www.writing.utoronto.ca/advice/using-sources/how-not- to-plagiarize) and to be familiar with the Code of behaviour on academic matters, which is linked from the UTM calendar under
the link Codes and policies.
