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

I am an italian teacher of chemistry. I like my work and new teaching strategies. Often some of my students can speak English better than italian and as I know how much important english is, I invite them to keep an english lecture on a particular topic for the whole class, including me. Your videos, tests and documents are really helpfull in this! Thank you very much
