Each class has short lessons and a hands-on project for you to work on, which can be shared in class for feedback and collaboration from the community. Skillshare will also recommend classes and "lists" — essentially a curated curriculum for a topic like graphic design or branding — based on your interests.
How to get started: Get a free account with just an email address. You'll have access to free classes on web and mobile.

Enroll in one or multiple classes with no extra charge.
Topics range from data science to personal development to linguistics to social sciences and more.
Each course is like an interactive textbook with pre-recorded videos, quizzes, and projects.
