General Information for Section 110

I teach on TuTh at 2:00-3:20 pm in LSK 201.

My home page is here [2].

I am always available after class to help you with short questions. Longer questions can be discussed at office hours.

  • if these office hours don't work, I'll modify them.

We will be using iClickers in this section. You can get an iClicker at the bookstore and register it following the instructions on this link [3].

The book for this course is Open (which means Free). You can download it from the link labeled "Course Notes" on the left or here:[4].

Check out the Course Calendar often to make sure that you don't miss continual important deadlines.

Course-wide policies


See the UBC Calendar entry for Math 102 for course prerequisites. If you do not satisfy the course prerequisites, you may find yourself automatically de-registered from the course once the term begins. The fact that you were able to register does not mean you satisfy the prerequisites.

Marking scheme

  • Final exam 50%
  • Midterm 15%
  • Online WeBWorK homework 10%
  • Quizzes 15%
  • Written assignments (OSH) 10%

WeBWorK points and the 5% rule: Each problem submitted to WeBWorK is given a point-weight and your total WebWork score will be counted out of 95% of the total number of WeBWork points. Thus, if there are a total of 400 WeBWork points this term, you can get 20 points worths of them wrong and still get the full 15% allocated to WeBWork problems. This is not intended as a point give-away. It is intended to account for the fact that, early in the semester, you will take some time to master using WeBWorK and we do not have the resources to evaluate every request for accommodation for every technical glitch you run into. Any requests for accommodation regarding WeBWorK points due to alleged WeBWorK glitches, computer crashes etc. are by default covered by the 5% rule.

For more information on WeBWorK and OSH assignments, see the Assignments page.

A minimum mark of 44% on the final exam is required to pass the course, independent of all others marks in the course. A student who has a total term average of above 50%, but scores lower than 44% on the final exam, will receive a term grade of 48%.

Independent work

You are encouraged to work in groups on homework assignments although independent effort is also crucial to learning. However, any misrepresentation of another person’s work as your own is considered to be academic dishonesty. In particular, directly copying someone else’s homework will be treated as a violation of UBC’s Academic Integrity Code. See UBC's policy on plagiarism for details.

Midterm absences, late or non-existent homework

If you are unable to attend the midterm, you must notify your instructor beforehand (preferred) or within two days after (in the case of emergencies) the exam date. In either of these two cases (and only in these two cases), suitable accommodations will be made. Undocumented absence from the midterm will be given a score of zero.

No midterm rewrites will be granted.

No late homework will be accepted.

Final and midterm exam regulations

For a full description of the final exam regulations, see the UBC Calendar page on Student Conduct during Examinations. In particular, notes, calculators, cell phones and other electronic devices are strictly prohibited from use during the exam. This includes use of cell phones for checking the time. The same regulations apply for the midterm.


Add/drop forms must be brought to the math department office. An instructor’s signature is neither sufficient nor necessary on an add/drop form. See the Mathematics Department registration information page for more information.

Re-marking requests

If you feel that a returned assessment is incorrectly marked, you can appeal that mark by writing a note that details your concern, attaching it to the assignment (if appropriate), and resubmitting it to the instructor within one week of the return of the marked assignment. For assessments marked on Crowdmark, this means you email your instructor these details. The note should include a summary of what you feel was incorrectly evaluated with some justification of the claim. Your work will be re-evaluated in accordance with the established grading procedures, and re-marked if necessary. Note in unusual circumstances, if you accidentally received a higher grade than earned, your final grade might decrease upon re-marking.

Section-specific policies


We will be using clickers for this class. Usually points are awarded for participation. Rarely, I may ask a few questions ("Quiz style") for correct answer points - But I will be very clear about when this happens.

You will need to register your clicker through Blackboard Connect (more about Clickers)

Your clicker grade will be part of the "Assignments" portion of your grade, and will be worth up to 5% of the final term grade. Do not worry if you miss a few classes or a few questions in a class. Participating in about 75% of the clicker activities will get you full points for the term.

Class etiquette

Cell phones should be turned off during class. Use of laptops in class is acceptable when computer software (e.g. Excel) is being discussed but not otherwise unless you use it for taking notes.
