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
This site has helped me study for test in my science class. The quizzes are spot on and the activities I can do really help nas well.
I have advanced in knowledge of calculus
I like this website because my science teacher has us read out of the books on this website and it's alot better then doing a powerpoint
CK-12 has given me a library of awesome resources to utilize that help me better understand the topics in my classes.
it has helped me learn many things that i would not have the chance to learn for a while
CK-12 has helped me be able to access information that would be in my text books when I am out of school and it is a great source for studying for exams!
its helped me learn a lot of things i was struggling with
you helped me get A's on my quizzes
CK12 helped me by improving my math skills by nearly 25 percent! Without CK12, I doubt I'd ever pass my math class!
You saved me from using an old gross textbook and helped me study and take notes in my biology class

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 While searching to remedy some of these challenges, I stumbled upon CK-12 which offers a solution to a semi-outdated text and no online option for students who have grown up in the technology age.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.

ck-12 is an amazing resource that provides up to date information that I can use to supplement our science textbooks. It also has leveled activities which helps when differentiating instruction. Keep up the great work!
