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 has helped me regulate my time of doing homework and being able to go back to a recording of a class if I need to remember anything for homework or notes.

It helped me raise up my grades by a lot by telling my teacher to send me some lessons on what I didn't understand that well.

I am an eighth grade student, taking geometry and without cK-12 I would not be able to take this course due to the fact my school doesn't have a teacher to teach it! So this helps me and my online teacher for me to learn geometry!

Comments from Educators
At a time when we were not able to continue paying for private instructions, we found this site and it was our salvation. We valued the set up and the freedom it presented to design the best course of action for 8th grade studies. Now moving on into 9th grade studies and more diligent record keeping, we are continuing on at the 9th grade level.
