A handful of kids petition to start Algebra 1 in 7th grade. The school offers a Linear Algebra course for them to take senior year.
The NYS science curriculum says you have to take a minimum of 2 years of science. One “physical” science (Earth Science, Chem or Physics) and one “natural” (Biology). Colleges generally like to see a year of bio, chem and physics. If you start the high school curriculum in 9th grade you have room for one AP, but our middle school offers HS biology and about a third of the students take it. AP Physics 1 is designed to be a first course in physics so you don’t have to take a high school level course first.
