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

Hi ck-12!!! congratulations!! Im one year older then you!! But....... you guys helped me get a A in science class and my teacher was very impress with my work I have. I just started when I first became a 6th grader, and I was pretty mad I had too start a new website. I always had gotten a D in science and I love science, so it hurt me to see I was failing. But I came home that day and my mom told me to do it any way, so I signed up and then BOOM!!! I fell in love with this website!! My teacher always told me that I needed some help with science, so I wold get on ck-12 and asked a helper for some help. My teacher always told me I could study more of a topic to get caught up with the other students, so I would hop on ck-12 and read,study,watch,and write down the topic. Since I started ck-12 I have an A in science,I have honor roll, and help other kids with science too!! So now that I am almost finished, congrats on having your 10th birthday!! Without you guys I dont know were I would be.Happy birthday!!! -Jasmine Whitfield-

cK-12 has helped me with supplemental learning for my students in Science 8th grade and HS Chemistry class. It's great since the cK-12 lessons teach the same scientific vocabulary that are in my standards. Thank you for making education free, accessible and easy to accomplish on a smart phone. You are speaking the students' language!
