i recently completed a course and got my final grade posted. however, i recently got an email saying i am under suspicion of academic misconduct of using my phone during a online proctored exam because i was looking around.
i am conflicted whether to tell the truth (which is that i did do what they are saying for two questions) or deny (i have not seen any evidence just what they told me they suspect).
i am very very worried and i’m not sure what the consequences for this may be. i am also worried and confused because the final grades were already posted and didn’t know they can do this after the semester?
any advice and thoughts would be appreciated.
