My oldest is in sixth grade, so I haven’t used these yet. But what I am looking at personally for high school biology is Wilson Hill Academy online courses or Kolbe Academy. (Kolbe you can buy the plans and teach at home or use their online courses.)
Both programs use the Miller-Levine textbook for biology. (Wilson Hill uses Campbell for AP Bio, which is pretty much the standard AP text.). Kolbe is a Catholic program, but several non-Catholic friends I know have used it and been quite pleased. Wilson Hill is Christian Classical.
Wilson Hill does “physics first” so the recommended order of the classes is different than the traditional Bio-Chem-Physics-AP. They do Physics-Chem-Bio-AP. So that is also something to take into consideration. The idea is that so much of biology is biochemistry now, so you need chemistry first. But to excel in chemistry, you need a solid foundation in physical science. After biology, students choose an AP science or physics 2.
