We have lots of courses on Coursera, and we get lots of questions from folks that don’t want to sign in and pay to get a certificate, and just want to audit.
This is possible. It’s subtle, but possible – here are the details.
The audit option will give you the full content of the courses, but you will not earn the certificates for completing them.
Note the Coursera terminology. A specialization is a collection of courses. Specializations may not be audited. However, each of the individual courses within the specialization may be!
Below are links to each of these courses within their specialization.
To access them in audit, select the course, and then click on ‘enroll for free’.

You’ll see a dialog like this. Important: Note the ‘Audit the Course’ link at the bottom. Do not select ‘Start Free Trial’.

This will give you full access to the content.
Below are each of the specializations, and I’ve put direct links to the courses within them. Follow the above process with these links to access them at no cost.
