Oxford and UCL were my two LNAT unis, and I got an offer for both, so I'm quietly confident I guess? I found the LNAT oddly enjoyable, but that was probably because it was at the same time as the Australian leaving exams, and so formed a nice break.
It's either the first Monday of February or the 4th when LNAT results are released (I think), and the alphabetical first half (by surname) receive their results roughly an hour or so earlier than the second.
