Well I think we all know who Bejazzled works for. 
Of course it's shit to mess around with exams being on, off, on again, teacher assessed. Teachers have been planning for this though, I know my S6's teachers are geared up for it and will be doing robust testing, monitoring, assessing.
This is a totally different scenario from last May's exams when it was all "normal" until March when the exams were pulled with about 6 weeks to go.
The SQA aren't setting exams, aren't marking exams, aren't collating scripts coming in from schools (and losing a few as they seem to do each year), aren't really doing much. Will get the marks in from school and issue certificates with those grades on for exams at ALL levels this year. It's purely an admin, data input exercise because we saw how well that worked out last year with their "algorithm".
The poor wee lambs at the SQA must be run off their feet.
