Trailhead is a platform where you can learn all the relevant skills needed as a Salesforce admin, developer or even a Salesforce user. It differs from any other learning platforms in the ways it works. Learning topics are organized into modules, which are broken up into units. At the end of each unit, you would be required to finish an MCQ quiz or complete a hands-on challenge, in order to fulfil the unit and earn its points. Trails are groups of modules that provide guided learning paths suited to specific roles or needs. You can also customize your own trail, and choose the modules that you’re most interested in without following a pre-existing trail. 

 
You can interact with other Trailblazers in the Trailblazer Community. In the Trailblazer Community, joining groups both in-person and online can help you grow your network. Additionally, topics allow you to learn more about particular issues. Find and follow prominent subjects, add topics to your queries to start a discussion, and get responses from Trailblazers all over the world. You can also adhere to Trailblazers with whom you connect or with whom you have similar interests. Your feed will be updated when you follow a Trailblazer, a subject, or a group.
