Each evening class in the modular program constitutes 15-20% of the in-class portion of the course. Students may miss a maximum of one-and-a-half classes in a course without an imposed penalty. Students missing two classes will be deemed not to have satisfied the requirements of the course and will be required to retake the course at a later date. Students in this position may audit the rest of the course if desired but will be considered "withdrawn" from the course. Registration fees will not be reimbursed in these circumstances and students will be required to pay fees when they re-enrol in the course at a future date.
