If a medical emergency or other extreme circumstance prevents you from taking a final exam, your Class Dean may be able to intercede on your behalf and issue a "No Examination Grade."
No, we cannot approve a "No Examination Grade" for travel. Talk to your professor about the situation, and they may allow you to take the exam early.
No. Once you complete the exam, your professor will record your final grade.
You will schedule your make-up exam directly with your faculty. You will have until the end of the second week of the next semester to complete it.
The nature of the evaluation you are given is at the discretion of the faculty member.
