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
In a lot of science, CK12 helped me start off my knowledge in science so I could build off that foundation. It has helped me in many various science subjects, from the EM scale to how rocks are formed. And it isn't ever difficult to understand or condescending and easy. And my grade in science is an A. So thank you, CK12!
