<p>How many AP courses are considered
MOST rigorous?
my HS offers like 21 AP courses</p>
<p>It depends on when you're offered all of these courses. I know personally that our school offers 11 courses, but you can only take three as a junior. So if the same is true, I'd figure like 6 over junior and senior year. If they're offered earlier however, I would def say somewhere b/w 8-12 depending on school scheduling format.</p>
