When you find a course that interests you, click on its name to go to Class Central's description, then select the green "Go to class" button on the right to go to the course page on edX.
If this is your first edX course, you will need to register with your email address, username and password.
On edX’s page click on the “Enroll Now” button and for most courses it will provide you with different enrollment options: Pursue a Verified Certificate (+ price) or Audit This Course (free)
If you want to look at the course before purchasing the certificate, choose Audit This Course. The course is the same and you will have plenty of opportunities to purchase the certificate later. Or you can pay and be eligible for a refund during the money-back period.
The exception is some professional courses that are paid-only. Clicking on Enroll Now will allow you to enter your credit card or PayPal details. You can find which courses are free and which are paid-only by looking at the price in the course information panel. Paid-only courses will display a price in US Dollars or your local currency, free will say Free Online Course and will list a price for the optional certificate. Pay-only courses are marked on Class Central information pages with a small green $ sign.
