I got the same thing, UCL and Kings for IR and I can't decide
I've heard good and bad things about both, some people say Kings student life is better, but some others say its way worse, theyre all from different departments though.
I think both campuses have a very different feel, but you have to be ready for the london life.
Im doing the IB, and the course point totals aren't so bad for either of them, but UCL has a higher requirement than Kings, which says something.
I am going to try to get into contact with some Kings and UCL current students for IR to see what they say.
If anyone has advice on finding people willing to talk about their course let me know, since I've been getting 0 responses on the universities UniBuddy function.
