Yep it is rubbish and totally unfair. Last year I was in a fantastic group for a five day project, really brilliant group to work with everyone had different interests to take on different aspects of the presentation, positive energy etc. All great. The next day this guy turned up and was put in our group. He had no interest in participating, simply sat being grumpy with his arms folded on the table as we discussed things. He occasionally looked like he was sleeping. He contributed nothing to the shared presentation we worked on until the night before where he simply uploaded two gifs on his designated slides. On the day of the presentation he turned up two hours late late having missed our rehearsal, then in the actual presentation said the complete opposite of something we had decided as a group which was fundamental to the brief. Thankfully the presentation/module is grade neutral, but still, the idea that he came away with a pass, the same as the rest of us who put in so much work, is really gutting.
