<p>For all classes but chemistry AA and AP:
90-100 A
80 - 89 B
70-79 C
60-69 D
59 and below F </p>
<p>I think every teacher rounds up 89.5, but there might be some meanie pantses that don’t/ Teachers also have the choice to round up borderline grades.</p>
<p>Chemistry AA and AP
87.x-100 A
78.x-87.x B
etc.</p>
<p>Basically, chem grades are curved. Other teachers curve, but they only curve tests. More on that later. An 88% is guaranteed to be an A in chemistry, that’s where the curve starts. Generally, about an 87% is an A, and if you get, say, and 86.8%, the teacher will round up.</p>
<p>APUSH tests are curved, APUSH essays are all graded out of 5 instead of 9 (not so that people get great grades on them, but because the teacher is insane and has given out two 5’s in his career and doesn’t believe that anything above that has ever occurred).
Every AP Calc BC test is graded out of 120%. So a 90/120, which is really a 75%, is an A.
AP Physics C tests always have either a bonus or a curve. The bonus is another AP essay, and is worth 10 points on the essay half of the test, which is 30 points total. When we don’t have a bonus offered or no one has time to do it, the teacher curves if we beg. I think Physics B works the same way.</p>
