We offer algebra, geometry, and science in every grade starting with kindergarten. It begins at a very elementary level. Depending on your career choices, by the fourth grade you will probably have all that you are likely to need. We do offer it in every grade as an option. The instructional programs in every grade from kindergarten to grade 12 are offered to all full-time students. When I was in school I loved science, but the science that I was forced to take went far beyond what was fun or useful. I went to a very elite private college but it was subsidized by the government and that strongly influenced the curriculum. All charter schools are government-sponsored and therefore the curriculum is controlled by the government. You cannot serve two masters.
