<p>Our school system did away with Earth Science for the advanced kids. They take bio in the 8th grade. They then take chem in 9th and physics in 10th leaving room for 2 science APs and more if they double up. They can take AP Comp Sci when they like as an elective. Some non science kids take Earth Science instead of physics for their Regents physical science requirement. And the fact is that if you look at our course catalog, it looks like physics isn’t a freshman course, but my son who was double advanced in math took it then. He took Chem via CTY in the summer so he could do 3 science APs easily. At any rate looking at a catalog on line won’t always tell you what really goes on in the schools. Some may have more flexibility than others. Our middle school was awful - you had to stamp your feet and go through hoops to persuade them that your kid should get accelerated, but once the kid reached high school pretty much anything the kid thought they were ready for they’d okay.</p>
