Final answer:
Andrew should report the incident to the professor or academic authorities to maintain academic integrity and contribute to a fair educational environment. Using or sharing the exam would compromise the trust and authenticity in academia.
Step-by-step explanation:
If Andrew wants to act with academic integrity, the best course of action would be to report the incident to the professor or academic authorities. This is because academic integrity is essential in building trust, understanding, and equity in the educational environment, as it ensures that the work submitted by students is their own and reflects their genuine learning. Faculties, administrators, resource providers, and students should all work together to maintain a fair and educational experience. Andrew should avoid the temptation to use the exam to get an advantage in his studies or to share it with his study group, as both actions would undermine the trust and authenticity valued in the academic community.
