Opt Out of Code Readability Reviews and the Leaderboard

The Code Readability Reviews and Leaderboard section appears when you can view a course that has a problem corresponding to Code Readability Reviews and Leaderboard. It also appears when the problem's materials have no deadline and the feature is not yet available to you.

Press Opt out of this feature.
A confirmation appears. Review the content and proceed.

After opting out, the code readability reviews and leaderboard will no longer be displayed for any course. Submissions you locked before opting out that appear on the leaderboard will remain.

Note: You cannot undo an opt-out yourself. If a service administrator later assigns you to a course after you have opted out, the feature will appear again.

Additional Notes
