Probably true for several of the UCs. The quarter system UCs seem to cover it in 2 quarters (20 weeks of instruction or 2/3 of a year). UCB on the semester system covers it in about 1+2/3 semester (25 weeks of instruction or 5/6 of a year) and adds introductory differential equations in the last 5 weeks of calculus.
MIT’s 18.01 appears to cover all of BC in one semester. Caltech and Harvey Mudd also accelerate calculus and make it theory intensive.
But it does appear that many other colleges consider the BC material the same as first year calculus, based on subject credit and placement policies.
