Thanks Btw what job prospects are you thinking of? Lol
Civil Service, Social Research (Perhaps along the lines of ONS/NatCen), Policy Research for a Think Tank, academic research (depending on funding), administrative roles in higher education (quite liked the look of working for the International Office at a university).
I specialise in Research Methods in Sociology - So things like statistics, interviews, philosophy of Social Science, policy research etc. So something along those lines.
It's popular amongst BBB students, because whilst it's not the most respected degree, a BBB will get you into a top uni for sociology, namely Bristol/Warwick/Manchester/Leeds etc..
