Hej,
I have a list of the interview/open day thingies (which I've volunteered myself to help out at!) if you wanted an idea of what kind of dates they tend to be, but obv they're invitational only for peoples applying this year.
Other than that, the main UCL open day is Thurs 2nd July (I've no idea why they only do one main one, and why it's in July). There will be a couple of UoL ones next september, but obv they aren't as detailed and UCL focused as the one in July.
there's some info on it here:
[link] and there should be a little thing of what the scandy dept is putting on for the day (not much, but hey) somewhere.
C-
