I wouldn't call myself fluent. I studied the language for the maximum time at college (4 semesters, spread out over three years for me because of study abroad), and spent two months in the Gaeltacht practicing at An tAcadamh through NUIG. I've also kept practicing with native speakers outside of that, and would love to get my masters in Irish (if I get it funded). I would say I'm comfortable, but I don't think my vocabulary is big enough yet, and, while I can read/write in advanced structures, speaking them really isn't as easy yet.
Edit: And this is all my guess; I haven't taken the TEG, but I'd put myself at B1/B2 level. Also, my reading and writing isn't as fluid as I'd like it to be (Gramadach na Gaeilge is used a decent amount, as well as dictionaries), though my listening is improving greatly with targeted practice.
Welp, for the first time in my experience Duo has screwed up. It wasn't even flagged as a typo.
I wrote: Pleann an dliodoir an teacht.
Yes, I know, it didn't make any sense to me either. "The lawyer discussed the come."
But I'm sick, forgot all about " t-acht" and hit enter...and Duo accepted it.
I suppose in Duo's robot brain it's just one different character? But no, that's WRONG.
Yes, I flagged it.
