At the end of the day teaching on a blackboard is cheap. As long as people can pass that course that week its fine . Students are prepped for exams .... not taught the subject.
Also if they are assessed 'competent' as opposed to 'not yet competent ' irks me . The lecturer told the last student "If you get anything past the 70% pass mark you are trying too hard" . Who ever thought up competency based training needs a punch in the throat !
