Broad? Limited to the fields of the professors, like today. The story talks about the FPI, and an extensive lecture by one of the examiners about this topic. Like today, expect professors to ask about their favorite topics. The FPI seems suitable for a 1st year physics course today, if not even at school. That example shows how one-sided his interests were, not how much of everything was expected.
