<p>The grade for my LS class came out, and I got a B+. I recalculated the points, and it looks like I got an A- though.</p>
<p>Maybe I'm not taking into consideration random factors like lab grade adjustments or whatever, but it sparked a question: Is it ever possible for there to be a grading mistake?</p>
<p>By the way, my LS class has no curve: participation, lab, midterms, and final exam amounted to 1000 points. When I added things up, I got 901.84, which is like, a dead 90%.</p>
<p>Thanks guys.</p>
