How is Law @ UTS? I might transfer there from Usyd because they have a straight undergrade B law, I hate doing combined.
I did a 1.5 years of a combined law degree at UTS and, for various reasons which aren't really relevant here, I'm finishing off my law degree at Usyd (graduate law) so I may be able to give some insight.
I had a couple of friends at UTS who dropped their second degree midway through and just finished the law part. They were really happy with their decision and I know at least one got a clerkship and grad job at a mid tier (if this is something you may want to go for). If you're sure about doing this, then this may be a good step for you, but otherwise it's probably a safer bet to finish your combined degree for a bunch of reasons. Even if you "know" you want to go into legal practice, another degree is often useful as intentions change over time. Keep in mind that even if you don't like your other degree, different subjects/electives can make a huge difference...
Anyway, sorry about the rant. In relation to your question, I quite liked UTS law: flexible timetables, recorded lectures, easy location etc. I have to say I prefer the Usyd experience, though, due to no tutorials (which I thought were a waste of time, though USyd is now going down that road) and better quality lecturers overall (imo). I went to UTS a while ago, though so things may well have changed.
Hope that helps...
