My last review was on UDACITY, which is quite different from cK-12, because UDACITY is designed mainly for higher level education while cK-12 is designed mostly for k-12 students. K-12 means kindergarten through twelfth grade, also known as primary and secondary education. cK-12 is a great tool for students and teachers from kindergarten to 12th grade in high school to use.
