Is it real? Yes. It’s a for-profit university.
It isn’t in league tables - it is a specialist university and league tables rank more traditional and not for profit universities.
Is it a good place to study law? That depends what you’re looking for. Personally I wouldn’t recommend it for undergrad law unless you’re a mature student looking for convenience. It’s stronger in postgrad as that’s the core of what it offered when it was the College of Law.
Is it famous? Not really.
