I got no help writing mine either, but so far I've gotten two interview offers from it. These would be my top tips once you get started.
• Write out everything you can think of in regards to your experience with animals, volunteering and any other achievements. If you haven't gotten any work experience now is the time to do that, try different places, zoos, vets, an abattoir if you can get it. The main thing is to show an awareness of the job, and whatever you've gained from it.
• Don't stress too much about having tons of incredible stories or anecdotes but it's good to haveone or two. I used watching a c-section and holding the newborn pup. Look up examples of personal statements (They have a ton here somewhere) and you'll see all the different stories from past applicants. The important thing is that you pick something that affected you and your motivation to be a vet.
• They should have your predicted grades but mention your strengths in regards to vet med, parts of biology or chemistry that might tie into your studies, I used skeletal system in regards to orthopaedic science but you dont have to be that specific.
It's important to remember that anything you mention in your personal statement can be brought up in an interview, so don't make anything up. Be yourself. Best of luck on your application hope it goes well for you next year!
