Well my year abroad was certainly useful, but Singapore is common law and in English so possibly not quite as useful but it depends really: some firms wil see it as an advantage, but in reality they have so many people who speak French it actually might count for jack all. Point is, do it if you're interested in doing it, not just because of some perceived recruitment advantage... if you want to do it, you can turn it into an advantage (and at the end of the day, an extra year of exposure to law certainly makes you better at it, statistically at Nottingham those who do 4 year courses perform better in their final year than those who do not).
