What Do I Need To Pass This Class? (December 2014 Edition)


It’s finals season, at least for colleges that run on a semesterly schedule, and a couple of my posts are turning up in search query results again. So I thought it worth drawing a little more attention to them and hopefully getting people what they need sooner.

The answer: you need to study a steady but not excessive bit every night from now to before the exam; you need to get a full night of sleep before the exam; and you really needed to pay attention in class and do the fiddly little assignments all semester, so, sorry it’s too late for that. Also you need to not pointlessly antagonize your professor; even if you don’t like this class, you could have taken others to meet your academic requirement, so don’t act like you were dragged into Topics in Civilization: Death against your will even if it does satisfy three general-education requirements at the cost of being a 7:50 am section.

Anyway, that doesn’t help figuring out whether you can relax as soon as you get 82.3 percent of the final right or if you have to strain to get that 82.6. So let me point to those: What Do I Need To Pass This Class? (December 2013 Edition) gives an expression for working out the score you need, and shows how to develop that formula, based on things like the pre-final grade, the weight given the exam, and extra credit (or demerits) that you’ve received, and is therefore good for absolutely any weighted-average based course grade you might have.

That also involves formulas, though, and I know that makes people nervous, so What Do I Need To Get An A In This Class? simplifies matters a bit by working out a couple common cases: for finals worth 40, 33, 30, 25, and 20 percent of the class, based on pre-final averages, what final exam grade do you need to get to at least a given level. Good luck, but you really shouldn’t be scrounging for points. Study because it’s fun to learn things and the grades will be good of their own accord.
