Usyd has an atar of 97.3 for Vet biology/DVM HOWEVER animal bioscience will be able to lead into the graduate DVM (total of 8 years) if you receive very good marks for the course. Usyd also requires you to get 150/200 for a stat test annd fill out a commitment statement
Before you go all crazy and decide you are going to go into vet here are my tips:
*Do some work experience and maybe volunteer at you local vet hospital - its a tough area and you have to realise that animal have to be PTS, and things can always go wrong in surgery
* Do some work with larger animals (cattle, horses) as well as with small animals
* figure out whether you enjoy or are good at science
* figure out if you have the skills to make it in vet
Also you have to realise that USYD has one of the lowest graduate employment rates (hence why I've made it second preference for myself) and it is an INCREDIBLY EXPENSIVE COURSE (Currently $10,000/year for 6 -> 8 years and it'll probably sky rocket with the new budget) and the starting wage (if you are lucky enough to get a job) is around $45,000/year.
If after you've done all this and are still certain this is what you want to do most unis have the following assume knowledge (not prerequisite but does require a bridging course if you haven't covered them):
*HSC Physics
*HSC Chemistry
*HSC Adv Maths
*HSC english
The following subjects are also recommended:
*HSC Biology
*HSC 3u Maths (Extension 1)
I wish you luck with finding information as I've found i know more than my school about a career in vet science.
I'm currently studying yr 12 physics, chemistry, biology, adv maths and standard english and am placed in about the top 5 for every science course and top 10 for the other subjects. Its a lot of work and a social life pretty much is a no.
I've also attempted to get as much experience as possible and posses experiences in:
*cattle
*sheep
*horses (10 years)
*dogs (compete and train in dog sports)
*clinical environments
