I wish my high school had covered a bit more than it did. We spent an age learning how to write a check and balance a checkbook . We did learn how to fill out the simplest of income tax forms and the basics of credit cards, but not a whole lot else. Though I must say that the credit card discussion scared me away from ever wanting one. The "monthly budget" thing would have been helpful, as it's not something I was ever really exposed to. I went shopping with my mom, but never really paid attention to the cost of groceries until I got to college, went off the meal plan my junior year and started having to buy my own.
