Advice to future students: Certainly don't worry. College is one of the most social places you'll ever find yourself in. Everyone is friendly and you'd have no problems making new friends. Even within a large course like Commerce you still have small class sessions. It's easy to start a conversation as more than likely you'll have similar interests. Once you know 1, you'll be introduced to their friends and you'll soon know another 5, and then if they all know 5 you'll know another 25 and all will be well!
I'd recommend UCD because it's easily accessible, great range of Courses, excellent facilities both educationally and on the sporting front, an active social scene which creats a great environment to spend the nest years of your life in. Simple as.
