There is no common CUET cut-off and no pass mark. NTA only publishes your scores. Each university, and often each college and course, makes its own merit list and cut-off from CUET scores, using its own subject rules. NTA's bulletin says it has no role in preparing merit lists. So a 'CUET cut-off' always means a specific university's closing score for a specific course and category in a specific round. Check each university's admission portal for its past merit lists.
