DD did not take a BC calc class but it is standard practice at her school that the IB HL (high level) math kids take the BC calc test after their junior year. Her teacher says that it is easier to get a 5 on the AP exam than it is to get a 6 or 7 on the HL math test. DD will take IB HL II next year. I have no idea what they cover but I've heard that some of it is pretty esoteric.
We have been asking about credit/placement for AP And IB classes on college vists. So far, DD has three 5s on the three AP tests that she has taken - AP Human Geography, APUSH and BC calc. I've been getting the impression that a 5 on the BC calc test gets you placement and/or credit at a lot of schools, i.e. MIT said that they would accept a 5 on BC calc or a 6 or a 7 on the IB HL math exam. It seems to be an accepted standard in a way that the non-math AP tests are not.
