As an alternative to what Dr. Foley is saying about points, take electrical engineering, which on occasion has been a low-points course, although there would obviously be maths requirements. Some electrical engineering students, on relatively modest leaving certificate results, end up doing PhDs or working at the top end of the industry.

Judges, for example, would have had very basic leaving certificates, because at the time, one could nearly go in to university and say "I feel like doing medicine today," or whatever it was. There was a period of time like that. Some of those people would have ended up at the top end of their industries.
