Found my email about accommodation, and it turns out I applied for Richmond Park (this seems, unsurprisingly, very popular), Sheavyn House and Dalton Ellis (though I've decided now that I'd rather be on Fallowfield, so that choice might come back to bite me in the arse).
Also, it seems (anecdotally) that people with offers that are already unconditional are getting places in their first choice of accommodation. Bit of a disadvantage for the rest of us, then.
