We had core requirements as well as electives. My core really needed more math. I picked up some math and geometry by osmosis through my electives, Shop, Agriculture, Drafting, Electronics... Math slipped through the cracks for me partly because I did 9th and 10th in a big school with over 1000 kids in my grade then moved to country school with 29 in my class for 11th and 12th. Or I could blame Jimmy Carter he was president all 4 years.
