Woah! I’m so happy I found you! I HATE PHYSICS, it’s not that I can’t do it I just really don’t enjoy it. I went on their website for bachelor of science and this is what it says... To me, it sounds like they’re saying at least ONE. What do use physics for? What ATAR did you get? Subjects? I thought biology would be compulsory as it’s to do with animals! Do you think we can exchange details and we can chat about this so it’s easier? Thank you so much again!
Biology isn't required because there's a bunch of things you learn about biology in high school that are just straight up, not relevant. Who cares about how plants produce energy if you're interested in how this dog's leg has a displaced bone? Why would it matter that this specific bird has this specific genus and came from that relative with genetic drift, if its owner wants to know why it won't eat? Biology is just a massive fucking field, and so it's easier for the university to ignore what you learned in high school, and just teach you what you ACTUALLY need to know. Of course, it's important to have a scientific background, which is why they ask for one of physics OR chem OR bio. In this case, it's the thinking that comes from having studied science, as opposed to what you actually learned.
As for what physics is used for, it helps you understand how joints work, helps you understand how different therapies work (ranging from typical physical therapy, to radiation and image based methods of diagnostics), and most importantly requires you to think differently than biology does. A lot of biology is memory based, being able to trace different pathways, or remembering the make-up of different cells and how they respond to different stimuli, and you'll be learning a lot about the biology of animals in your degree. Physics, however, is a lot more problem-based, and uses different parts of the brain than typical study of biology allows you. Hence, it's important that you've learned those analytical skills for the rest of your career, as well as have a basic understanding of a lot of fields (ranging from electricity, to mechanics, to radiation and light)
On top of all this, don't forget that the course you're looking for isn't JUST for people wanting to become vets. Some people who study this may go on to work at zoos, as scientists, or any other number of fields, and you'll need different skillsets depending on each of those. So, they're not going to just teach you things you'd need to know as a vet.
My thoughts on whether you take physics or not - it doesn't matter if you match the requirements for physics if your ATAR isn't high enough to get into the course. You're more likely to do well in subjects that you enjoy, and this is something that pretty much anyone who has done VCE will tell you (they did better in the subjects they enjoyed because the content absorbs better, they were more motivated to study those subjects, etc.). So, if you hate physics to the point that you don't think you're likely to study it much, or absorb the material as well as you would in another subject, then fuck it - an extra year in learning is honestly nothing compared to your whole life.
