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 helped me finally start to get good at math! I was struggling for years, but homeschooled my sophomore year, I started getting a grip and I am now about to start my Senior year. Now I can graduate with my friends and go to college to be an EMT like I've wanted to for many years! Thank you!

Ck12 has revolutionized the manner in which I teach. This magnificent educational asset has taken the text book out of the classroom and made learning accessible to students anywhere there is a internet connection

I am a first-year chemistry teacher in an under-funded charter school. Our books are almost 10 years old and our lab doesn't have a complete stock. While searching to remedy some of these challenges, I stumbled upon CK-12 which offers a solution to a semi-outdated text and no online option for students who have grown up in the technology age. Thank you for allowing me to add your site as a resource and have options for useful tools to teach my students. Your site helps to make me a better teacher.
