Generally speaking, the majors that don't need professional background in Britain mainly include media research, business management, business marketing, English and so on. These are mainly concentrated in the liberal arts field because similar majors are not very technical. Generally speaking, they may need students' own understanding of culture, personality and non-academic characteristics, that is to say, although students from any background can consider it, they should choose according to their own characteristics.
The other is a law major at the University of Sheffield. There is a two-year master of law, which is specially prepared for students who have no professional background and want to study law.
As for the popular major finance, most of the majors in financial accounting management in the business schools of Bristol University and Leeds University only need related majors, while the financial majors such as York University, Reading University and Bath University need students with engineering or mathematics background, which means that the school does not exclude students from other departments, but the premise is that mathematics is good. What is rare is finance that really doesn't need any business background, such as Leicester University, university of stirling and so on.
In addition, the pedagogy of individual schools does not need a professional background, and those who have worked in the education industry will have an advantage in application.
