there are actually two forensic science courses offered....
1) Bachelor of Applied Chemistry (Honours) in Forensic Chemistry
2)Bachelor of Biomedical Science in Forensic Biology
From what I heard from Professor Roux at the Gifted and Talented students progrmme at UNSW, the job opputunities are miniscule in Australia...so I say a person of your calibre is better off doing an advanced science degree and trying to enter that field...cos if that fails then at least you have a decent degree to fall back on...whereas come to think of it there are not so many oppurtunities if u have just an applied science degree (which by the way is nowhere near as enticing as a plain old BSc for prospective employers)
So all I can say is that if you're really motivated and think you can get a high GPA, then go for it~~ Otherwise don't
