Isn't King's higher on the league tables? I know it is for Classics.
Ok, um...well, I always knew that London was my first choice, after I was rejected by Oxford (their loss, we're over it) - I just love the city and the culture and....oh, just everything about it. I applied to King's and UCL as I wanted to be in central London (so not Royal Holloway!) and LSE don't do Classics. I completely fell in love with UCL, the way everything was just there right in Bloomsbury (it's a Virginia Woolf thing), the people! I was interviewed at UCL by this adorable old Greek professor who was just so lovely, as were all the other staff and students I met, whereas I loathed the woman doing the open day presentation stuff at King's (in spite of her glorious name: Ismene Lada-Richards), and I always felt really lost inside King's. Plus UCL gave me a higher offer and they've recently set up a Classics with a year studying abroad thing, which looks amazing (I love my travel), while with King's I would've had to go for Erasmus and all that, which just seemed like so much more hassle. The things that made me hesitate were: King's seems to have a higher reputation and has marginally better TQA and research scores (by one mark each, I think); and King's stages an annual Classical play performed in the original Greek, which I thought would be so much fun to do. However, the Classics Society at King's was, they admitted, pretty much dead (the girl doing the tours and just re-established it), while UCl has a very active classics soc. King's also seemed a bit desperate to have me (naturally!), for a place with such a good reputation: they gave me a relatively low offer (BBB, which is the same as all y other places except UCL) and didn't even ask for an interview, which made me a bit suspicious. UCl seemed to have more accommodation closer to campus, and had more connection with UoL as a whole - what with ULU being so close and everything.
Basically, I chose UCL because it seemed like a nicer place and it was a bit easier with UCAS, since they tend to look somewhat askance on your insurance being higher than your firm.
And that's my 'I love UCL' rant over...
