Hi! First of all, good job! As someone who has offers from a few law schools, I hope that I can give you suitable advice!
Do you take the EPQ, or are you eligible for any contextual offers? It may lower your grade requirements, since Leeds and Sheffield normally have AAA entry requirements, but will lower it to AAB with an A in EPQ. Additionally, are you only applying to England, or are you open to applying to Scotland as well? Additionally, although these are your AS predicted grades, they might improve in the future if your teacher is willing to predict you a higher grade. How high of a prediction do you think you can get based on this? (For example, my teachers weren't willing to predict me much higher than my AS, though I know of a few of my year group who has jumped by approximately 1-2 grades)
Based on your grades, possibly:
Aberdeen
Dundee
Strathclyde
Lancaster
Manchester-- you would need to achieve AAA at A-Level, but they do not consider AS levels within their admissions process
These are a few of the options, but you just need to check out each individual uni website to see their entry requirements (note that some unis such as LSE and UCL needs at least a B in GCSE Maths). Some unis are more lenient than others in their entry requirements, but a Leeds representative who came to my school literally said "If you meet the entry requirements, and you have a decent personal statement, you'll get an offer.", if that gives you any comfort!
I was in the same boat as you, and this might not help much, but try not to be too nervous. As you're already set on Law, start your wider reading, make notes on whatever seems interesting, and start thinking about your personal statement. Feel free to ask any questions!
