What's in the Twelfth-Grade Kit The final year. Calculus, world history, economics, and a medical investigation course that doubles as college-prep science. Literature wraps the four-year series, writing goes to the craftsman level, and thinking skills go deep — formal logic in both kits, philosophy in classic. STEM includes game programming and a full engine build — projects with enough complexity to hold a senior's attention. The kit also includes interview skills prep and the Timberdoodle High School Planner to make transcripts and life after high school that much easier. Classic and nonreligious kits differ in history, science, economics, and thinking skills — compare tiers below to see what's in each, and use the customizer to swap anything that isn't the right fit.
