For Physics, most high schools that offer AP Physics 1 teach it as a full year course. Substantially fewer even offer AP Physics 2.
For calc, it’s a mixed bag. Some offer AB as a full year followed by the BC topics as a full year. Others offer BC as a full year encompassing both AB and BC topics. Still others offer both options, with the top math students taking the more accelerated option.
As a data point, my HS did not offer either AP Physics 1 or 2, just a regular HS physics class, but did offer AP Physics C as a follow-up course for those interested. For calc, they offered the third example I listed.
