What classes should I take online before Freshman year?

So far, the only high school classes I’ve taken are Algebra 1 Honors and Earth and Space Honors. The classes I can take are those available on FLVS.

I think you are in good shape…you want Alg 1 so you can get to calculus by senior year, and the earth science will let you take Bio, Chem, Physicsa and then an AP version of one of those.
