It's time for me to think about breadth now, I think, given that it's something I can't avoid next year (yes that's directed at everyone who thinks I worry too early). I don't even know what breadth subjects would interest me; I like music, but my last music exams required too much general knowledge and musical history knowledge, and the course outlines seem to suggest a significant amount of music theory, so that's not too appealing.
Now, given that I speak Chinese everyday at home, can read and write to a comprehensible extent and can comfortably watch Chinese television series (which I do all the time), roughly what level of Chinese would I be put into, and would it be worth doing?
