<p>Your school is doing it properly. Calculus BC approximates a one year freshman calculus course in college. Students who are advanced in math should be able to handle that. The other schools are doing a disservice to advanced students (especially the top students who are two years advanced) by forcing them to take calculus at half speed.</p>
<p>When I was in high school decades ago, the only math course available for those who completed precalculus in 11th grade or earlier was calculus BC (in one year).</p>

<p>The high school may be double-dipping by having you take the AB test one year and the BC test the next year, counting it as “two AP tests taken”. However, colleges will not give you any credit or placement for AB if you get credit or placement for BC, assuming you get high enough scores (according to the college’s standards) on both.</p>

<p>Calculus at community college would be like BC in pace and difficulty, unless it is “calculus for business majors” or something like that.</p>
