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

IT HELPED WITH ALL OF MY HOMEWORK!!!!!!!!!!!!!! We have our lessons on the readings and they have really helped me learn. There is an occasional grammar issue and a misspelled word but other than that the practices and all the other things are really good for a 6th grade children's science class!! By the way HAPPY ANNIVERSARY!!!!!!!!!!!!!!!

CK 12 was useful as I could download the text books for use with me students. Now I cannot do that anymore. Congratulations on your 10'th anniversary, you have gone from useful to useless for me.
