I can't help but find the bias towards Law at A-Level so frustrating to think about. Well, I'm biased too, since I'm currently doing it, but still.
Out of all my subjects (History and English) Law (CIE) is by far my most difficult. Unless you do the course it's difficult to explain not only the scope, but the depth of the teaching.
My law teachers are actually all lecturers/senior lecturers at the local law school (an affiliate of the university of Liverpool) and teach us almost exactly the same subject material, albeit more condensed.
There is no way that when I start uni in September I won't have a slight advantage. Especially since Tort and Contract will be in my first year and those are my A2 subjects.
