<p>I think the Prof made a mistake and I’ve seen the exact mistake with my D in high school. In her case, there was a “score” column and a “total point” column. Grade is calculated by total number of points earned divided by total possible points. The teacher entered 5 for her score, BUT also entered 5 for total points, which just made it another assignment, NOT extra credit. Teacher should have entered a zero in the total points column.</p>
<p>Your D should definitely bring this to his attention.
From my experience, mistakes are made more times than one would imagine from people you think would know how to do things.</p>
<p>Edit; I bet the same mistake was made for all who did the extra credit…have your D have other e-mail as well.</p>
