<p>School systems write their rules differently. Our school has now substituted AP Physics B for Honors Physics. They still teach regular and I think you could go from regular to either AP Physics B or C depending on where you were in math. In NY you don't have to take x years of math - you have to pass certain levels of math. But you have to have four years of English and pass a Regents test in English which most kids take junior year.</p>
