This exam cannot be paused and returned to later.  Please ensure that you have allotted uninterrupted time to complete your final exam.

Proctored Exam

The MAT 120 final exam is a proctored exam.

In order to take a proctored Final Exam, students must obtain approval from AAU (see the Allied American University Catalog) for their choice of proctor prior to taking the exam.  The Proctor Request Form takes 48-72 hours to process; therefore, it is important for students to budget their time accordingly so that they have enough time to schedule the exam after the form has been processed, but before the course end date.

See the ARC for more details regarding AAU's proctoring policies.  Read the Proctored Final Exam Instructions, Who Qualifies as a Proctor?, Proctor U, and Important Notes sections carefully.

For further questions, please contact your Program Success Advocate.

The student will have three (3) hours to complete the exam.

What will the final exam look like?

The final is composed of multiple-choice and true-false questions.
