There will be weekly homework assignments, usually due on Mondays. Late homework will not be accepted. A selection of problems will be graded. I will drop the lowest homework score.
Graded homework will be available for pickup at the Math Learning Centre
There will be two midterm exams, on Friday October 6, and Friday, November 10. There are no make-up midterms. If you miss a midterm for a valid medical reason, the weighting for the final will be adjusted. Other than this, no re-negotiating of the weights of the different components of the overall grade will be considered.
There will be a final exam during the December exam period.
The following applies to all exams in Math 300: No calculators, notes, books, electronic devices or aids of any kind.
Your grade will be computed as follows:
Final Exam: | 50% |
Midterm 1: | 20% |
Midterm 2: | 20% |
Homework (lowest score dropped): | 10% |
Check back here for homework assignments and solutions, notes and links as the term progresses.
