It is complete nonsense and indicates to me the OP doesn't really understand the field as well as they think. As someone who has gone through all the exams, the upper-level exams test aspects of the industry in incredible depth and is more about regulatory requirements than any specific model. OP may have a decent understanding of reserve models, cat models, or financial forecasting, but those are not a core part of upper level exams (although you would certainly be expected to know it).

I spent hundreds of hours memorizing flashcards on US healthcare regulations as well as some things about the Canadian healthcare system. By far the worst years of my life.
