4 Laboratory/Tutorials Week Tutorial (ENG 310) Lab (ENG 309) Week of Jan 9 Week of Jan 16 Electromagnetism - Week of Jan 23 Electromagnetism - Week of Jan 30 DC Machines - Week of Feb 6 - Lab 1 (DC Machines) Week of Feb 13 Transformers Week of Feb 20 Study week Study week Week of Feb 27 Midterm Midterm Week of Mar 6 - Lab 2 (Transformers) Week of Mar 13 Induction Machines - Week of Mar 20 - Lab 3(Induction Machines) Week of Mar 27 Power Electronics - Week of Apr 3 - Lab 4 (Power Electronics) Important Notes 1. All of the required course-specific written reports will be assessed not only on their technical/academic merit, but also on the communication skills exhibited through these reports. 2. All assignment and lab/tutorial reports must have the standard cover page which must be signed by the student(s) prior to submission of the work. Submissions without the cover page will not be accepted. The cover page can be found on the departmental web site: Standard Assignment/Lab Cover Page 3. Should a student miss a mid-term test or equivalent (e.g. studio or presentation), with appropriate documentation, a make-up assessment may be scheduled. Alternatively, the weight of the missed work is placed on the final exam, or another single assessment. This may not cause that exam or assessment to be worth more than 70% of the student s final grade. If a student misses a scheduled make-up test or exam, the grade may be distributed over other course assessments even if that makes the grade on the final exam worth more than 70% of the final grade in the course. Make-up assessments cover the same material as the original assessment but need not be of an identical format. 4. Students who miss a final exam for a verifiable reason and who cannot be given a make-up exam prior to the submission of final course grades, must be given a grade of INC (as outlined in the Grading Promotion and Academic Standing Policy) and a make-up exam (normally within 2 weeks of the beginning of the next semester) that carries the same weight and measures the same knowledge, must be scheduled. 5. Medical or Compassionate documents for the missing of an exam must be submitted within 3 working days of the exam. Students are responsible for notifying the instructor that they will be missing an exam as soon as possible.

5 6. If a student is requesting accommodation due to a religious, aboriginal and/or spiritual observance, he or she must submit a Request for Accommodation of Student Religious, Aboriginal, and Spiritual Observance AND an Academic Consideration form within the FIRST TWO WEEKS OF CLASSor, for a final examination, within two weeks of the posting of the examination schedule. If the required absence occurs within the first two weeks of classes, or the dates are not known well in advance as they are linked to other conditions, these forms should be submitted with as much lead time as possible in advance of the required absence. Both documents are available at Full-time or part-time degree students must submit the forms to their own program department or school. 7. The results of the first test or mid-term exam will be returned to students before the deadline to drop an undergraduate course in good Academic Standing. 8. Students are required to adhere to all relevant University policies including: Undergraduate Grading, Promotion and Academic Standing: Student Code of Academic Conduct: Student Code of Non-Academic Conduct: Undergraduate Academic Consideration and Appeals: Examination Policy: Course Management Policy: Accommodation of Student Religious, Aboriginal and Spiritual Observance: Establishment of Student Accounts for Official University Communication: 9. Students are required to obtain and maintain a Ryerson account for timely communications between the instructor and the students. 10. Any changes in the course outline, test dates, marking or evaluation will be discussed in class prior to being implemented. 11. Assignments, projects, reports and other deadline-bound course assessment components handed in past the due date will receive a mark of ZERO. Marking information will be made available at the time when such course assessment components are announced. 12. If you have taken the course previously and are currently looking to get a laboratory exemption, then you must fill out this form: Approved by: Course Instructor Date Approved by: Associate Chair or Program Director Date
