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 has helped me get better grades in class!
As an 8th Grader, CK-12 has been a truly amazing resource not only for school, but for curing my curiosity outside of the curriculum. I want to thank everyone who contributes to this incredible organization!
CK-12 helped me and know I get more and it helps me learn more and get things even better than I did before.
Hello! I greatly appreciate all that CK-12 has done to help me throughout my time in biology! I look forward to the amazing things that CK-12 will do in the future!
