Have you been to the UK much? I need to go to Barbados at some point. Maybe a cricket tour or something.
Politics workload was minimal to be honest. Lots of extra reading on top of 4-8 contact hours a week that many people didn't do, then it was a case of knuckling down before exams/essays.
Law will be different. Expect 20+ hours a week and plenty to do in the library for a couple of extra hours.
I lived in James Baillie in first year and it was OK. Private housing second and third year. Want to go back to halls next year at Charles Morris because it is the best in my opinion. Right next to all lectures and gym... just need to find somewhere to park the car, as it is rammed around there during the day
