In order to apply for CS in college, how many years of Physics is recommended in HS?

To offer another perspective on how much offerings vary across high schools…

My children’s HS offered ‘Regular’ Physics, ‘Honors’ Physics, and both AP-C Physics classes, but did not offer AP 1 or 2. Advanced math/science students could enroll in AP Physics C as Juniors, concurrent with BC Calc enrollment. That cohort then moved on to the second AP C class Sr year and many also took MV Calc, but that was not an AP class.

Meanwhile, other students could enroll in either the ‘Regular’ or ‘Honors’ Physics Jr year, and then progress to the first AP C class Sr year, or drop physics and elect a different science for Sr year. Some Jrs also elected to enroll in AP Chem Jr year.

My son’s college math major requires two fairly advanced Physics courses, including quantum mechanics.
