UCC itself is wonderful. It's a highly respected University internationally. UCC was a very relaxed university I found, I really do miss it's atmosphere!
Area of Study
I'm doing Law and French. No regrets about choosing this course - it'd still be my number one choice if I was filling out the CAO again.
I find the facilities very good. But then again I do the majority of my studying at my apartment. The library/computer suites always become crowded around exam time and can be difficult to get a place to work!
If you can afford it then I'd recommend getting student accommodation in 1st year rather than moving into private rented housing. Its much easier to to make friends and settle into life at college. The only downside can be the price which could be much higher than private renting.
Clubs and Societies
Clubs and societies in UCC are brilliant and there's always something to do
