I didn't have to take a competency test, they had an equivalence-list that included Irish.
Ordinary Leaving Cert Irish counts as Grade 11.
I could ask for the exam, but I'm inclined to trust their rating system. Given that I barely passed Ordinary Irish 12 years ago, I think that take a shot at an Honours Irish test after 12 years of no-Irish would be foolish.
So I'll hopefully get enrolled in the Japanese course that starts in 3 days....
Win!
