<p>Most schools in my county allow freshmen to take AP Human Geography and/or AP Environmental Science. Almost nobody takes both of them because it means sacrificing an elective like P.E. that’s a graduation requirement. My school doesn’t offer AP Enviro, so I just took AP Human Geography. AP English Language is restricted to 11th graders, and AP English Literature is restricted to 12th graders. Besides that, most APs are based on prerequisites, not what grade you are in. Here’s what I mean:</p>
<p>To get into AP Chemistry, you need to have biology honors, and it is highly recommended that you take chemistry honors, but some skip that second part and take it as a sophomore.</p>
<p>To get into AP Biology, you need to have taken both biology honors and chemistry honors/AP. Thus, almost nobody takes it as a sophomore (unless they do chemistry over the summer online or at community college) - it’s generally a junior/senior. My school bent the rules for me and a couple of other kids this year and let us do it without chemistry.</p>
<p>AP French Language is generally only a junior/senior class because you need to have French I-III, and you can’t take a level higher than French I in middle school. However, I know of two native speakers who took the class as sophomores simply because they were able to speak, write, and read at that level.</p>
<p>AP US Government is a senior class. However, I know a kid who’s taking the class as a junior along with AP US History, and a friend and I are taking it online (we’re rising juniors) in order to get that credit out of the way.</p>
<p>AP World History is generally a sophomore-only class, but every few years there is a kid who takes world history honors as a sophomore and ends up taking AP World as a junior or senior.</p>
<p>AP Music Theory doesn’t even have a grade requirement. If you pass an entrance exam, you get to take the class. Some kids can do this as freshmen, while others can’t even pass it as seniors.</p>
<p>There are more classes, but I think you’re getting the point.</p>
