From what I've found during my research into law schools is that the best ones are all gonna be A*AA, then there's a few that are like AAB that are still pretty good, and after that I struggled to find any with a good reputation/ that I'd heard of below ABB/BBB.
They probably exist but I personally stopped looking at that point. Law is competitive even without having scraped your way onto a law degree so I didn't see the point in looking any lower.
Northumbria takes in based on UCAS points that I think works out to roughly straight Bs or maybe an A or 2. I'm not sure given the new tariffs, but that's probably gonna be my "safe option" when I start applying.
Hope this helps, and of course, I may be slightly wrong. This is only what I personally gathered so no one shoot me please aha.
