Academic Integrity is the practice of approaching your coursework and exams with honesty, trust, fairness, respect, responsibility, and courage. It's this practice that ensures that your degree (and everyone else's) is worth the hard work, time and commitment that you've put towards it.
Approaching coursework and exams with integrity isn't hard, but sometimes the details of what is acceptable can vary a little by class. Your first point of contact to ask questions is your professor or TA. Remember that, since classes are remote right now, you will have to contact them electronically!
