I got a conditional offer from those universities and i am not sure where to study because all of them are great university with reputation. So I wanna know that which course is famous for each university.

I think that your indecision must be narrowed down to Queen and Aberdeen. I would put UEA totally out of the picture. Now, as regards choosing between Queen and Aberdeen, you have to keep in mind that Aberdeen is much respected in the field of private international law and oil and gas, while Queen, because of its location and being a University of London school has a very good reputation in commercial law. Although I think that Aberdeen is very well regarded in such subject also. Personally, I would vote for Aberdeen at first, without any further details about your plans and objectives.
