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
I am a above average student and cK-12 has helped me learn at my own pace. Learning at my own pace has helped me keep up the A's. Another way cK-12 has helped me and lots of others in my grade learn. Is I created a study group called math and I send out assignments whenever I can. I also know that we can learn from each other.
