Hi,
i was offered both last year and went with Nottingham for multiple reasons
Firstly, the overall university experience. Wawrick is very campus based, its geographical position makes it harder to get off campus to ie other cities, nights out off campus ect. Nottingham is a lot more city-oriented. Travel around the city is very easy and you Nottingham Trent close by if you want to be social with others. If you are a city person like me, then Nottingham is more suited for you. If you prefer the campus oriented feel, then try Wawrick.
As a current Nottingham law student i am slightly biased, however i would definitely recommend Nottingham law school! It's links with MC firms is amazing, we hold the national law fair and often have esteemed solicitors coming in to offer us opportunities. I have also been told by multiple recruits that Nottingham is particularly targeted after Cambridge and Oxford for graduate recruits. The law school is also widely known for its superior research. If you are going for a career in commercial law as i am, i would most definitely recommend Nottingham.
However i must point out that Nottingham Law is not one of those 'ill survive on 40%' universities. It is widely known among MC firms for being harsh markers. As long as you're willing to put in the work then you'll be fine.
I'm surprised at the entry requirements this year, last year they were A*AA, but either way they are surprisingly lenient with entry, i have friends who missed their offer by 1 grade and still got in.
Once again this is clearly biased as i am a Nottingham student, but this is my attempt at giving you the information you might need to help make your decision. At the end of the day they are both great Uni's and i'm sure you will do well at either.
