Comments from Students

I have chronic pain that doesn't allow me to go to school. I had a really hard time homeschooling until I found this website. CK-12 has helped me to be able to get an education until I am able to go back to school. Thank you.

CK-12 has helped me a lot. It has helped me understand certain subjects in science and much more. In my opinion CK-12 is one of the best educational websites there is.

Our school just gave each student a chromebook, making us 1:1 school. Only 1 of 2 in our district. Our school is Title one with many obstacles to overcome.

Trish P.

CK-12 has helped me with a lot of things such as science, reading, math and social studies. I like using CK-12 because it is extremely useful and I suggest you to try it out also.

I don't understand why it works like this but, it is amazing so I like it but, I think it shouldn't have a login for the students the teachers should only have a login. I love this website it helps me with my learning a lot so, thank you and have a good y
