Thank you, Chrisrolinski and Sylvester, for your advices.
I am hoping to do my Phd in one of the Scandinavan countries if possible as I have a little knowledge of the language and think it would be easier for me to pick up from there. However, I hope the course can be conducted in English. I actually do not mind doing it in any of the other EU countries if the Scandinavan countries do not have the course that I intend to take.
