Last year I wrote a meal and points calculator to help with figuring out how much you should be spending to not run out by the end of the semester (and to not have tons left over at the end of the semester). You enter how many meals/points you have remaining and choose a meal plan, and it tells you how much you’ve been spending every day and how much you should spend every day for the rest of the semester so that you end with nothing.
It’s here: http://samdk.com/points
(It’s been updated for this semester for at least a couple of weeks, so if you’re using it already you can ignore this.) Questions/comments/suggestions can be left here for a couple of days, after which they’re probably best sent to my email (sdefabbiakan@wes).
