    Grading and policies

  • Term marks may be scaled up or down on a classwide basis, depending on performance on the final exam. This is to ensure fairness across all sections of the course.
  • You have to submit only your own homework, own quizzes, own clicking, etc. Although you are welcome to study together and discuss the homework with other students, the work you submit (electronically, on paper, or via clickers) must be your own. UBC policies on cheating and plagiarism are extremely strict. If in doubt, enquire before submitting.
  • Missing a quiz or submitting work late normally results in a mark of 0. Exceptions may be granted in two cases: prior consent of the instructor or a medical emergency. In the latter case, the instructor must be notified within 48 hours of the missed item, and presented with a doctor's note immediately upon the student's return to UBC. No make-up quizzes will be given.


    There will be in-class quizzes every second Friday, as scheduled above. Preparatory questions will be posted here in advance of the quiz. You must work all problems in advance of the quiz in order to be prepared.

    Computer lab assignments

    Lab assignments will be assigned, due every 2 weeks. To complete the labs, you will need to use Matlab. A basic student "unbundled" version of Matlab can be purchased and downloaded from Mathworks, Inc: www.mathworks.com for $49. You do not need any additional toolboxes for this class. Alternatively, you can use the department computer labs. More information will be posted later. Lab help will be available at times/locations TBA.

    Practise midterm

    A practise midterm (not to be turned in, not for credit) will be available in late October.

    Final Exam

    Information related to the final exam (common to all sections) will be posted here.
  • Previous math exams. Note that different topics receive more or less emphasis in different years.
  • UBC Math Exam Resources wiki.
  • UBC Math club. Will sell you some previous exams with solutions. Carefully note their opening hours.
