Why Students Love CK-12!
Take a look at what these students have to say about CK-12!
Wonderfull! like that it’s really to the point and precise. There’s lots of pictures and diagrams that are helpful when you are trying to learn.
My teacher made these textbooks, and it has everything that we need for this specific class.
It’s really accessible so it’s easy for the whole class to get on and we just go!
We use it every day because there’s something new that our teacher wants us to look at!
My CK-12 book is really nice because it has all of the information I need in it. Instead of hunting for all of the words and questions I have, it’s all there right in order
Comments from Students
Before I take a dissection test, I take the quizzes on here. Then when I take the test, my partner and I only miss one or two. So thank you for helping me get good grades.

CK-12 has helped me breeze through geometry in a private school which did not offer the class. The ability to do everything on my own gave my teacher the time he needed to teach his other classes and helped me earn my high school credit for when I advance

CK 12 was useful as I could download the text books for use with me students. Now I cannot do that anymore. Congratulations on your 10'th anniversary, you have gone from useful to useless for me.
