hi, i am currently a first year student at tcd - last year their requirements were 590 points - which is 4A's in A level as 1A = 150 points; this year they lowered the requirements but also introduced the HPAT test, i don't know the exact amount but you should be able to find out through their web site
www.tcd.ieJust need to clarify, the university in ireland only look at your grades - obviously now the HPAT is introduced your personality also is taken into account, but the HPAT gives a score and that is added to your total score, and thats all the universities look at. So, if you meet the minimum score, you are in (cept if all the places are already filled with people that has higher points than you)
The universities that does medicine in ireland are: TCD, UCD, RCSI, NUI Galway and Cork; i would say all 5 are competent enough to teach medicine, and it does not matter where you graduated from. Having said that - TCD is currently ranked number one in all the irish universities, and is ranked 49th in the world; UCD is the second which is ranked below 100; so if you believe in these tables then TCD would have a better international reputation than the rest of the ones i mentioned above.
As a trinity student i actually think UCD/RCSI's course is better structured than ours - but then its just my personal opnion.
O and about fees, I am currently paying free fees at the moment, which means i only need to pay for the registration fees (around 800 euros) and thats it for the year; having said that living in dublin is incredibly expensive. I THINK you are categorized into the free fees status if you hold a british passport and have reside in britian for the past 5 years or so, which was my case (or if you are an actual irish citizen)
Anyhow... best of luck with the application; and maybe i'll see you next year!
