Braces; haven't really researched this properly. We may have to go private
Trips home; the overall price difference allows for €850 (annually) which would easily bring me home twice a year, not accounting for the extra I would earn from a part-time job
Language barrier; I'm already learning the basics but will surely learn German when I am totally immersed and interested
Course work; this would have been gradually more difficult in Dublin too. When I am not challenged I lose interest. This will push me!
