"I know of people who studied Life Sciences, but deliberately avoid taking any immunology modules as they know these are the killers. So they managed to scrap a 2nd upper. But when people start to talk to them about biomedical issues, they scratch their head (as they don't understand), leaving these people bewildered at how they gotten their degree. Reason being you can't talk in depth about biomedical stuff without touching on immunology."

I think that the point you raised here is more applicable and valid for technical skills and hard subjects. However, for softer subjects like Communication Studies and Social sciences which Jeraldine is taking, the courses and projects don't really help one that much in their future professions.

As such, I would say follow Jeraldine's advice if you are taking soft subjects. But don't heed some of them if you are in IT, engineering or science.
