Ah I’d forgotten that, helps explain the increase in using grinds to maximise results.
There used be a stigma to getting grinds, mainly seen as devices for low achievers trying to get middling results. A two year leaving cert was seen as being a bit cuter, for the more average students to get a much better result.
It must have been stopped as it was getting to the stage that it was a deliberate choice for many students, for medicine in particular the rewards are so high that taking an extra year to get there made a lot of sense.
