To access the content on this site you need to register with the site (just once). This requires an email address and selecting a password.

You can register by clicking on the "Sign Up" link in the main menu bar, or by clicking on any of the "Enroll for Free" links associated with each individual course.

(Or you can click this link.)

FYI, doing this will also put you on the Critical Thinker Academy email list. I send out periodic emails to let people know about updates to the site.

Once you're logged in, you get access to any of the course modules by clicking on the "Enroll for Free" links. When you log in, all of the courses that you've enrolled in will be available under the "My Courses" link.

That's it!
