Unable to open Assignment

I am auditing this course and I am not able to start or open both the assignments of week 2 and also of week 3. as soon as I click on assignment name it shows purchase to submit, but does not opens.

Hey @ashitpatel, I don’t think you can access the assignments without first purchasing the course.

Earlier I audited same course and I was just able to access somehow. But they have changed the access policy I guess.
