Work through each module in order. Every module ends with a short mastery check. 10 modules total, then one longer check across the whole path.
Guided Learning mastery checks are part of every paid plan, with a 7-day free trial. Read freely below, and you'll be prompted to start a trial once your free taste of a mastery check runs out.
