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.

Save Money Teaching Multiple Children

Our Additional Student Kit includes only the consumable items for this grade level, saving you money when you are homeschooling more than one Twelfth-Grade student this year. Purchase one curriculum kit, then buy only this money-saving Additional Student Kit for the second student.
