Where should I apply UK unis?

What year you applying? You too late for Oxford and Cambridge this year. With your stats, maybe have a pop at UCL, LSE. KCL, Warwick, QMUL. Hey, I suck at maths too and I'm doing law (second year).

Could I ask how important lnat is and what score to aim for at Bristol and then what score at UCL and LSE

Bristol uses these weightings for assessing Law applications - 20% GCSEs,40% A level grades, 40% LNAT. And a mid 20s LNAT score is usually enough to be in contention for an offer.
If you intend to apply this year, make sure you register and actually book an LNAT test slot asap. If you are applying next year, go to the Open Day this year - its free, just register and go - Undergraduate open days | Study at Bristol | University of Bristol
Any of the books like this will be good prep for LNAT - The Ultimate LNAT Guide by William Antony, Dr Rohan Agarwal | Waterstones - you can get 2nd hand ones on Ebay, it doesnt have to be 'this year's edition'.

Still got time since applying next year for Oxbridge hopefully.Looked at UCL,LSE,KCL sadly you need a 6 in maths even for law so my first choice would then be QMUL.If not,Warwick,Manchester,etc. Glad I`m not in this alone cus I keep seeing these perfect law applicants with all 9s+maths a level🤣
