CHI makes the curriculum and lessons available online. With this method, the course of study may be purchased at a better price and without the cost of shipping.

Students may study the content of their textbooks and videos through their computers. They will also have the option of printing the full texts and/or exercises at home, or of completing the exercises in a notebook, either by copying the questions or simply writing the answers or procedures.

For those whose parents purchase the curriculum in black and white, students will now be able to study online with color material, at a lower cost than with the black and white printed material. For those who use color curriculum, the savings will even greater with the online option.
