Thanks skieurope. I am aware of the AP board pre-reqs. His high school pre-req requires an A in Chem Honors and Pre-calc for AP Phy II. The fast paced course he did includes material similar to a year-long, algebra-based introductory course in high school physics (a usual prerequisite for advanced physics courses such as AP Physics C or IB Physics). Here is a link to the syllabus: https://cty.jhu.edu/summer/docs/syllabi/phyw_1.pdf
