It ok, but there is better

Ok, can get very frustrating as to complete a assignment, you need 100 perfectness right or 10/10. Even a 9/10 is a restart the whole practice.

CK-12 - Digital curriculum at its best is a great resource for everything from full textbook-like curriculum (called FlexBooks) to individual multi-modal learning resources such as videos, digital interactives, and simulations.
