@Hopeful0304 That’s interesting about Stevenson since I believe that the new head there was the old head at Hotchkiss and Hotchkiss has (had?) an integrated science curriculum for Freshmen but allowed a choice in Sophomore year. My son took AP Bio as a Sophomore but that was a a bit unusual. He followed junior year with AP physics. His first year course provided enough of a foundation to handle it. Of course, if Hotchkiss is moving away from that model then there’s likely a good reason why.
