There is not a "total points possible" in a class system in place. There are assignments/tests in each class. There were anywhere from as few as 8 graded assigned/tests in social studies to as many as 37 in geometry in my son's first semester. On top of that some assignments are "formative" and some are "summative". Summative assignments are weighted more (anywhere from 67% to 90%). They compute two separate GPAs for summative and formative and then add them together based on their weights. For example is that a student may have the following summative grades: 3.5 2.5 3 3 3.75 2.25 3.25 Assuming none of these summative grades are weighted more than another (which can also happen), his/her summative grade would be 3.03 (the average of all of them). This would then by multiplied by the summative weight to produce his "summative GPA" and then added to his weighted "formative GPA" to produce his/her total GPA for the class. Not really as complicated as I may be making it sound. Here is really what I'm having trouble wrapping my head around: Example 1: Math grade for Student A: 3.24 Math grade for Student B: 3.01 Example 2: Math grade for Student A: 3.25 Math grade for Student B: 3.24 In example one, in Waukesha, both students get a final GPA for math of 3.33 (even though, in reality, one student achieved a grade .23 points higher than the other) In example two, in Waukesha, Student A gets a final GPA in math of 3.67 and student B gets a 3.33 (even though only .01 separated the students in reality) Again, does this make sense to anyone? Yes, is in 4 AP classes, but they do not earn college credits, nor are they weighted any differently at the Freshmen level. They are labled AP because they are more "advanced" than the "standard" classes that a freshmen is expected to take (example: AP prep English 9 vs. English 9). Teachers make recommendations as to who should take AP classes. There are 18 AP classes at the Soph, Junior, and Senior levels that are weighted more in regards to GPA. Whether or not any of these courses count towards college credit, I'm not sure.
