But what about older kids? My kids are going to be seniors, applying to colleges. Is my daughter supposed to teach herself AP BC calculus herself? AP microeconomics (which she knows nothing about). AP Spanish literature (her 6th year of Spanish)? In high school there are several age groups in some classes. Kids take algebra in 7th, or 8th, or 9th, or 10th. Keep in mind that scoring 4’s or 5’s on AP exams usually count as college credit, even if just electives, saving thousands of dollars. Classes would have to be taught on the lowest level, many have passed that level years ago.
