How do I reuse a program with younger student?

If you know you are going to use a program with a second (or third) student, be sure to purchase each Consumable item for every additional student. Consumables are things like workbooks and activity sheets and are listed conveniently in the Recommended Items tab on the product page. You'll only need to get a few items; the vast majority of your literature-based program should be completely reusable.
