CK-12 has been an awesome resource! It provided much needed Biology resources for my daughter when she was a freshman.

CK-12 reading selection and real world applications are engaging and informative. I like that the content is aligned to NGSS and that the lexile level and academic language support make the content accessible to challenged learners. The PLIX interactives are graphically -appealing concept reinforcements.
