<p>A school that has students two to four grades ahead in math is not a typical “subpar” school. This is especially the case if it offers post-calculus-BC math courses either natively or through a dual-enrollment setup with a college. Actual “subpar” schools would have students struggling to complete precalculus by senior year (the normal grade level for math) and may not even offer calculus due to lack of student interest.</p>
