<p>My high school had Physics (both non-AP and AP - neither was a graduation requirement) but didn’t have computer science, economics, or any math beyond Calc BC. In cases where there’s a nearby college it may be expected that students take these classes at the college (as was the case at my high school). In other cases, the school may just be too small to offer it.</p>
<p>Depending on your definition of “high school” my high school was either the biggest or 2nd biggest in Michigan when I went there. </p>
