I would like to apply for GLR0. Does my chosen language have to be one that I have previously studied, or one that I have not previously studied?

It does not matter whether your chosen language is one you have studied before or not. The starting level of the language is flexible and will be tailored to your prior knowledge. 

If you have already have an A level in one of the languages available, we offer advanced language courses covering Business, Current Affairs and Culture at a high, in-depth linguistic level. These courses require a high A level grade in the language concerned, or equivalent. At an even more advanced level, we offer courses focusing on the use of the language for Professional or Academic Purposes, or on Translation Skills.

You may also be able to take optional courses organised by the linguistic department concerned (subject to timetabling constraints and departmental approval). It may also be possible to study two languages.
