Best wishes to your DD for her Uni/College applications.

Here, ‘Down Under’, we are about six months behind in the school year, so DS still has plenty of time to put together his application(s). I think the Uni he is applying to is the only one which has ECs as a compulsory part of applications. Other universities encourage ECs by offering bonus admission points for selected ECs, however, for his application, if he doesn’t include and show evidence of them, the application will not be accepted. I don’t think the ECs actually have to be relevant to the course. Our universities are slowly becoming more like those in the US but not quite there yet.
