I am a rising sophomore at Cupertino High Schoool, and I have been using
your website for my studying, and review for quite a while now. It has
been extremely helpful, often times it explained things better than my
teacher. So thank you! It is a secret hobby of mine to type up
info/notes from class, and turn it into a more compressed “textbook.”
Although, this does take quite a lot of time it is extremely helpful for
finals and the SAT’s. Although my peers teased me for doing the extra work,
your site inspired to continue making my study guides.

I am a huge proponent of the open-source philosophy,
especially where it pertains to education. CK12 has proven that a
sensible, intelligently-organized text can be assembled under
Creative Commons. Our district has adopted “Chemistry, 2nd Ed.” as
our primary text for all general chemistry sections. We printed a
classroom set of 40 textbooks for less that $200. Students now carry
USB flash drives, not 10 lb paper textbooks!

We love the materials on your website. This is a wonderful way for our teachers to experiment with using web-based resources in our classes. Thank you!

First, I used your Biology textbook and (very) successfully completed the CLEP biology test!
I am now attempting to do the same for a Chemistry CLEP test. There are questions at the end of every lesson within each chapter. Is there any resource with the answers to those questions? They are very similar to the CLEP tests. Using questions from your text would be invaluable to help me study.
Thank you.

I love the work you guys are doing. I’m a physics
teacher in Denver Colorado and I have been “following” the Peoples physics
book for a couple of years and the work you guy have done to that book
is incredible.

online from free resources and I will be including your incredible learning
resource as a link on my website so that people can access your knowledge
base. Thank you so much for this incredible service to humanity that you

Thank you to everyone at CK12. You have been hugely important in my
development as a teacher over the last several years. You are impacting the
lives of many kids here in North Carolina.

First of all, THANK YOU for assembling this extraordinary
chemistry text. I am implementing it across the board for general
chemistry at Kirksville High School (Missouri).

Just discovered your site through a link on the creative commons website.
I was very impressed with the design, content, and ease of use. I’ll be
using it for my kids during the summer to give them a jump start on next
year.
Thanks!

Dear CK12 Support,
I want to share with you that last year I used the CK12 Biology Text,
Student Workbook and the Teacher Resources. I found these to be incredibly
useful. They were my primary text and resource and they were comprehensive,
well written and well organized. I especially appreciate that the workbook
and resources were highly aligned with the student text. Taken all
together, they provided a very adequate text for both my honors and
standard sections of high school biology. As a result, I look forward to
using other CK12 products.
Many thanks and kindest regards.

Awesome. Thank you. I work with kids with learning disabilities and the
text seems to be very appropriate for them. Lots of examples, good reading
level, to the point.

CK-12 has created the most powerful digital text on the market and in the process is pioneering the digital text industry. The free Flexbooks allow for easy editting, ability to save in multiple file types, and student interactivity. After finding CK-12 Annandale Middle School decided against purchasing textbooks for our 8th grade science classes and used the savings and some grant funds to purchase iPads that the students use in class. Making the leap to a digital learning environment has provided the students at AMS with skills and experiences necesssary to be successful 21st Century learners.

I really appreciate your organization. I am 73 years old and it’s been over 55 years since I studied Chemistry. Four years ago when we were foster parents we adopted our last three charges. Now I have a 10,12 and 15 year old daughters. I’m disappointed with our schools here in Az so I’ve been homeschooling them for 2years now. This year chemistry is one of our subject so I’ve built up a lab and with help Home Science Tools and Robert Thompson (homechemlab.com) I am putting together A super Chem. course. I did this for my first child, now 48, I graduated from UCR and is an organic chemist for Babcock Labs in Riverside Ca. As I registered with your website I see you also have many other text books available. I download the Biology book. I am an electronics engineer and love teaching since the early 60s thanks to the USN. I pray that you will continue a wonderful service. Thanks again.
