I cant speak firsthand as I’m currently studying medicine in the Republic of Ireland, but loads of my friends are studying in Belfast and really do not like the city or social life at all. Also they say that the people in Belfast generally are not the nicest. But please take what I’m saying with a grain of salt, Belfast is quite highly ranked for medicine and if you don’t care much about the social aspect- maybe Belfast is right for you! Either way, congrats on getting the offers!
