Any tips on how to calm down before a practice mock/ actual UCAT? I tend to get really nervous and stuff up VR as a result
It's useful to know a bit about nervousness/anxiety/fight or flight response (if you don't already), and then pick some strategies to target the symptoms that you experience. For example, if you find it hard to concentrate or settle down, mindfulness might be useful, if your heart and resp rate ramp up, then a quick breathing exercise might be good.
Any strategy you go with you will need to practice using over and over and over so that it's second nature on the day and has become part of your routine (that way you're less likely to forget it, you're proficient at getting the most out of it, and your body has actually had a chance to learn the grounding/relaxation part and what it feels like so that it's easier to achieve when you need it most).
The most efficient mindfulness exercise I've come across is called Three Things, and you can modify it as much as you like, but basically it's a grounding exercise that gets you to focus on your physical environment, rather than on your thoughts (because it's your thoughts driving the anxiety).
Go through this list deliberately and with focus
1. Three things you can see that are... round/green/sharp... whatever you like. Find them in your surroundings, briefly take deliberate notice of them, then move on to...
2. Three things you can hear... the third should be listening to yourself take a breath in and out through your nose, the first two can be whatever noise is around you, then move on to...
3. Three things you can feel... again, the third should be feeling the air against your nostrils as you take a breath in and out through your nose, and the first two can be whatever you're sitting on, for example, of the feel of your feet on the solid ground.
Then... into the exam.
This is just an example, by the way. You may find it useful, you may not, and there are about a gazillion others out there if this one isn't for you
