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

CK-12 has helped me understand things more clearly and it is easier to pay attention to because of the videos and other different ways to teach. A textbook is hard to understand because all you see or hear is words there is no video that shows a diagram

At a time when we were not able to continue paying for private instructions, we found this site and it was our salvation. We valued the set up and the freedom it presented to design the best course of action for 8th grade studies. Now moving on into 9th grade studies and more diligent record keeping, we are continuing on at the 9th grade level.
