This book is great. The links that the authors provide are interesting and relevant. Having a workbook to go with the material is a great bonus!
it’s amazing cm-12 Biology
i think this is the best for kid. my kid used to iPad for learning. now he really happy to read this book.
This textbook is well written, easy to understand, and the interactive format is amazing! CK-12, please make interactive versions like this one for your other textbooks. I've downloaded others, such as chemistry, but the interactive format makes this one much easier to use and learn from.
Great Education resource!
Wow… Could not keep the book down
By Sameer Nayak
I was actually having fun reading CK-12's Biology book. In a single sitting I read about everything from Proteins, Lipids etc. to the cell structure without ever feeling that I was studying. Great job CK-12.
This is a great interactive Bio book that I'm sure a lot of fellow students and teachers will find helpful. Love the simplistic design and great interactive content.
This is the future of Textbooks
CK12 making interactive books using iBooks Author......wow! This is the future of school textbooks. Free textbooks which are aligned to state standards, and are interactive, and can be updated using iBooks 3....great! Please make more using this method as I know the school I work for will jump on them.
