Yes. You may choose as many or as few courses as you wish, from whatever grade levels you wish, for any student. You may also mix grade levels (e.g., 5th grade math; 4th grade English; 6th grade history). We encourage parents to individualize the courses and paces selected for their students. So at enrollment pick a main grade for lesson plans, then let us know if you wish to depart from that “main grade” level for individual subjects , and we will send lesson plans for those subjects, without charge, as long as the student is enrolled.
Yes. Anyone may purchase any of the materials in the Academy bookstore.
