Assignments
Late homework assignments will not be accepted, except for unusual circumstances, which should be communicated with the instructor before the due date. You can discuss the problems with your classmates but copying work is against University regulations.
Exams
There will be two exams, including a midterm exam, and a final. All examinations will be closed book and notes. The necessary formula will be provided to the students.
No make–up exams will be given — if you have a legitimate and documented justification (medical condition), arrangements may be made in exceptional circumstances for you to take the exam somewhat earlier or later, or for a missed exam to not count towards your grade.
