Does this make any sense to anyone? Why don't they just give the students the scores they earned. If you get a 3.21 in a class, then count the 3.21 towards the overall GPA. Why is there this need to make an adjustment up or down? I am not a teacher, but it kind of makes sense to me... You get "points" in a class, but your class points are not equivalent to GPA points. Your class points determine your letter grade, and each letter grade corresponds with a certain number of GPA points used in calculating your weighted average overall GPA. Think of it this way - if the class was based on 1000 possible points, then we still need to convert that to a letter grade to assign a GPA. It seems as though the school probably assigns everyday homework/test grades on a scale of 0 to 4 instead of by assigning letter grades or percentages to each individual assignment/test for a class. (That seems to be the only explanation that doesn't involve artificially boosting GPAs.) I had one teacher who used a similar system when I was actually still in grade school - then he somehow converted these "everyday" scores into a letter grade, which corresponds to a number of GPA points. I graduated in the mid-2000s from a high school where we didn't get "extra credit" for AP classes and where the max was a 4.0. My class was actually the very first one where they didn't offer a 4.3 for an A+. You could still get 3.7 for a A-, 3.4 for a B+, etc. (I think each score was actually rounded up to one decimal place, hence a 3.4 instead of 3.3 or 3.33 for a B+.) In my class there wound up being six people tied for a 4.0, but the school had a pre-set tiebreaker based on some combination of # of AP classes taken, ACT score, PSAT score, extracurriculars, etc. to determine who was the valedictorian and salutatorian. Just out of curiosity - is your son actually in 4 AP classes that he can get college credit for taking a test at the end of the year? Granted, I went to a private school smaller than any of the Waukesha schools, but they didn't allow anyone below juniors to take AP classes, and even then they wouldn't let you take more than 2-3 at a time, just because of the added workload. Does "AP" still mean a college-level class that prepares you to take a test to earn college credit, or does it mean just any "advanced" class?
