<p>At my school, the honors sciene track takes Earth Science (with labs) in 8th grade (then the NYS regents test), Biology 9th, Chemistry 10th and then AP Chem, Bio or Physics R/H/AP 11th and 12th (only 3 sciences, including ES required). The regular track just starts a year later with Earth Science in 9th grade which is required. Most people take physics in senior year. I'm personally glad I took Earth Science, it was an interesting course and I love rocks and minerals so that was fun for me.</p>
