Homework Quizzes:
Student will keep a homework portfolio will not be directly graded. There will be 10 homework quizzes. These will occur at the start of each Wednesday class (except for Midterm weeks). Each quiz consists of 2 homework question, and is worth 1% of your course score.

Algebra Workshop:
The Algebra Workshop is a drop-in workshop, open at least 3 days per week, where students may come from assistance with problems and questions during its working hours.

Calculators:
These will be permitted on examination, provided they do not have graphing/linear algebra capabilities nor online access.
