I did initially want to do a double degree in Commerce/Law but I love Melbourne Uni - the surrounds, the subjects, the lecturers/tutors etc... it's great! And I think it's more beneficial to do law as JD as the students will come from more diverse areas and be there because they actually want to study law, not because they got 99.95 or whatever, which is sometimes what happened in the old model. Also, they still offer a guaranteed pathway for school leavers who actually already have a passion for the legal field, so some of those talented students are not lost. This is also positive because areas of law are multidisciplinary so details can sometimes be discussed in a JD class that wouldn't be possible in an LLB class. I also love the idea of breadth subjects as not only are you exposed to your area of specialisation, but you get to experience things outside your area, giving you even more depth. Depth of experience is, what I believe, distinguishes JD students for LLBs. As well as this, before studying law, you've already established a way of studying etc. in your undergraduate subjects as you are ready in that uni is quite different from high school. Lectures max 60 students as opposed to undergrad degrees where they have hundreds at times.
Anyway, I'll be staying at uni for at least 7 years, then after that, another 2 after some work experience. That totals 9, but I reckon that's okay

It's only a year longer than what it would take in a double degree and I need actuarial accreditation and the like, so it might actually be necessary. Thus, all things considered, I think that the Melbourne Model may not be such a bad idea.
