If their exams can't be trusted they shouldn't be trying to instill trust in their exams. What you are suggesting is literally that they should commit fraud to hide their incompetence. The fact is the system they've created can't be trusted. So no, it's not an imperative for them to make people trust the system, it's the opposite. We all know full well that they aren't in a position to run the exams correctly, and yet rather than accepting that and working on ways to move forward without the exams, we've decided a consensual hallucination that the exams were fine is the best option. Oh, and screw the kids who couldn't submit the exams. It's more important that the the college admissions board has an easy life. And as if that's not crazy enough, the examiners have decided to try and entrap the students. If you don't see how insane that is - that more time is being spent trying to entrap sutdents, than to be honest about the veracity of the test results, you've really fallen off the deep end.
