In fact, the formal examination of CET-4 and CET-6 didn't set a passing feng shui. Generally, a report card will be issued if the test score is above 220, but only if the test score of Band 4 is above 425 can you register for Band 6. Therefore, many candidates will default to a passing score of 425 for Band 4.
Graduation certificate:
The relevant education departments of the state have not stipulated the relationship between CET-4 and university diploma, nor have they said that you cannot graduate if you fail CET-4.
