My course is about 2/3rd /60:40ish female, at a guess.
A tutor told us earlier this year the university has to positively discriminate in their admissions process to allow more females into the course, and therefore into the legal profession. I am unsure if this is a decision the Law School took upon itself, but I think it's more likely to have came from the Law Society.
There's my seasoned law student answer if that helps at all !
