What is the difference between 4-Day and 5-Day?

4-Day programs are great if you have an extra-curricular or co-op type program one day a week. 4-Day programs give you a schedule and materials for only four school days per week -- 144 days in the year -- so you can comfortably fit everything into your busy schedule.

5-Day programs include a complete school year's worth of material -- 36 weeks/188 days. These programs include about 20% more books. Many customers who school only 4-days per week find they love the books so much, they buy a 5-Day program and use the "extra" books over the summer.
