done a legal studies degree (had a lot of subjects with criminology students [it was practically the same course])
doing law now (I did not do my previous degree because I needed to do a degree before doing law, it was because my Year 12 ATAR was shocking)... I can tell you that criminology is a billion times easier than law... criminology is also more fun and more thought provoking
law = greater career opportunities... criminology = working as a shitty social worker, court registrar, etc... (NOTE! there are certainly good jobs you can get with a criminology degree... they are few and hard to come by but... eg: ASIO, AFP, Australia Crime Commission, Adult Parole Board, Corrections, etc... with further education you can branch off to become a forensic psychologist or you can branch off to do a Juris Doctor... There are heaps of good opportunities but getting into these positions require you to weather strong competition... The employment market for law is just as competitive if you ask me...)
(One of my mate who graduated with me is now working with the Victorian Commission for Gambling and Liquor as a Policy Analyst... so don't be fooled you can get some mad jobs...)
law = better hands down... (if you can handle it)... (but that's just my opinion you may end up doing criminology and really like it and become really successful in it...)
only need to do an undergrad course (and it can be any bachelor degree) first if you want to do a Juris Doctor... other than that you can get by with just doing an LLB (undergrad law)... Juris Doctor = LLB that cost 3 times more...
***NOTE! that might look like jibberish... I don't care, I'm doing 10 things at once***
