Hey, I am starting Graduate Entry in UCD this year, if you have any specific questions let me know. The GAMSAT is a pain, but I didn't do all that great in it (got bang on 50th percentile for this year). I only started studying for it properly about a week and a half beforehand so I wasn't expecting to get in. I did alright in my interview and had quite a wide variety of work experience and good references, and 2.1 in my degree, so they obviously consider everything together. It is however very expensive and they only have around 10 places (usually less) for EU applicants each year, the rest is made up of US/Canadian students.
