Time wasters

During revision, most students in class would not want the lecturers to waste time. There are so many exam questions to discuss and many issues needs to be resolved. Example when a lecturer are wasting time:-

• Telling too many unlaughable jokes
• Never answering questions properly
• Passing off other's work
• Bitching
• Only provide a 'can pass lah' kind of answers (low grade)

Sometimes students are not that stupid, we know which lecturer put in the effort and which doesn't.
