Your professor hands back marked exams, and tells the class to carefully check the grading, in case an exam has been graded unfairly. You realize you answered a question wrong, even though you knew the correct answer. You scribble in the correct answer and resubmit the paper. This is an example of academic misconduct.
Tests submitted for re-grading may not be altered in any way, even if you did know the correct answer at the time of the exam.
