Smartsite gradebook shows grade change without reason

<p>my smartsite grade in one course changed from 83% to 85%, i assumed it was the final, but i cant see the final on the list of things that have been graded, then today i check again and now it says 86.7%, and nothing else has showed up. is this an error, or is it possible that certain things have been changed that aren’t viewable to students? thanks!</p>

<p>my grade randomly changed again, back to 85% lol.</p>
