This website is excellent for highly achiever. In addition, it offers the opportunity for in-depth exploration.

The CK-12 platform offers a clean and intuitive user interface, making it easy to navigate and explore the vast amount of information provided. The platform can teach both introductory and advanced topics and can be picked up in less than 10 minutes. While the platform may have some limitations, such as clunky layout and cumbersome class setup, it can be a valuable tool for engaging students based on their interests. One teacher reported struggling to generate interest in science until they combined CK-12 with Newsella and NPR, which led to increased engagement and independent exploration by students. Despite some navigation challenges, the CK-12 platform can be an effective tool for promoting student engagement and interest in various subjects.

Overall, this resource has many good things for students to learn on their own, with critical thinking questions to stimulate their thought process. Once again though, the navigation and controls leave something to be desired.

This site offers very useful activities for students to prepare for tests. There are great options for classes in the STEM field.
