Coursera Progress is a free Chrome extension developed by herman. This extension allows you to have complete control over your Coursera progress. With Coursera Progress, you can easily manage your lecture videos, quizzes, and assignments.

One of the main features of Coursera Progress is the ability to mark lecture videos as watched or unwatched. It adds an empty (gray) checkmark next to all lecture videos, giving you the option to check or uncheck each lecture as you progress through the course. This feature helps you keep track of which lectures you have completed and which ones you still need to watch.

In addition to managing lecture videos, Coursera Progress also supports managing quiz and assignment progress. You can easily track your progress on quizzes and assignments and mark them as completed.

Coursera Progress keeps the data for each course separately and automatically syncs it across different browsers when you sign in to Chrome. This ensures that your progress is always up to date, no matter which device you are using.
