    Free auditing on Coursera and edX

    Most paid courses on Coursera and edX have a free "audit" option that\'s well-hidden:

    1. Find a course you want.
    2. Click "Enroll" or "Start course".
    3. Look for a small link that says "Audit only" or "Full course, no certificate".
    4. Click that — you get all the videos, readings, and quizzes free.
    5. The only thing you DON\'T get is the printed certificate.

    Free audiences for big names
