Bristol v UCLWatch
One important thing about Law with a Language at Bristol - it means you wont have a choice of doing all the available Law units because half you timetable will be the other subject. A better idea can be to apply for straight Law, and switch to the 'Study Abroad' pathway at the end of your first year. This means you still get a Year Abroad in France, do whatever French culture/arts/law units you can there, and improve your language skills etc, but without compromising your Law choices.
PS. There are lots of good reasons to go to Bristol : https://www.youtube.com/watch?v=khM7tjui86Q
