Get Ready for the Final Exam!

June 26, 2015 Leave a comment

Here are the current grades to date. Read your line carefully. To calculate the score you need to go up or down one grade, I assumed everyone will perform on the final exam exactly the same way, relative to all other classmates, that they performed in the rest of the class

That’s reasonable overall, but of course, in reality there will be some students that do better than they usually do, and some worse.

Notice that the students who currently have an A can’t get any score that will give them a higher grade. (Duh!) But also notice that they’d really have to do terribly on the final just to go down a grade (again, assuming everyone else performs in the same way they have all semester, relative to all the other classmates).

None of the current B students can get an A unless they do very well, and one or more of the A students do very poorly relative to their past performance. And so on.

One of the things I hope my students can learn from this is how unlikely it is that a final exam (at least in one of my classes) will change your final grade. I give so many grades during the semester, I have a very precise idea of where you all rank relative to each other. In my classes, last minute miracles–and last minute disasters–are extremely rare.

That doesn’t mean you shouldn’t study! To keep your current grade, most of you need to perform about as well as you normally do.
