Apparently any Vet course, Category B + C I've heard, Society and Culture I hear alot of people find a bludge, same with IPT, General maths (cause apparently it's like Yr 9 and 10 again)Hospitality, studies in religion,PDHPE...really any subject becomes a bludge subject once you stop doing work in it and caring about it. Or if you can do well in it with considerably less work in it (which depends on the individual, some find this with english or geography or economics)
All based on what I've heard people at my school say.
