The way our district has set it up is that if you don't take CC 2/3 in 7th grade, then you can only ultimately take AP AB Calculus, not also AP BC Calculus.
I think fewer kids will take Calculus in our district with the CC, not more.
I still don't understand. What is CC 1? (6th or 7th grade) Is this the only year they compact?
What my district is looking at is both a compaction at junior high level and another possibly compaction at the high school level. Allowing multiple paths to Calculus by the end of H.S.
Is your district one of those who only offer BC Calc as a 2nd year? Where I am you take AB OR BC Calc not both. That is the way the College Board intends it, but I know not how all schools implement it.
