Nothing. Signing up for Site Access is completely free and gives you full access to our entire content library; everything that was available at launch. Once you sign up, you're a Site Member.

Site Access is our free membership. It's how you become a Site Member and unlock our full library of scenario-based courses, exams, documents, and community features at no cost.

The Mastery Track is our collection of credential-yielding courses; a step above our free library content. These are paid courses, priced individually based on length and depth of content, that lead to a credential upon completion.

Pricing varies by course, based on its length and content. You'll see the exact price listed on each individual course page.

Yes; you'll need free Site Access first. Once you're a Site Member, you can purchase any Mastery Track course you're interested in.

Mastery Track courses run on either a 30-day or 90-day access window, depending on the course — you can complete it at your own pace within that window.

Your access to that course ends when the window closes. If you'd like to continue, you can repurchase the course to get a new access window.

There's no need for a free trial; Site Access itself is free and gives you full access to our entire library right away.

No. Pricing does not change for existing Mastery Track purchases you've already made.
