I absolutely agree with the above. AAA is a great set of predictions so congrats and good luck achieving them! Since you're planning on taking a gap year then I would encourage you to focus on your A levels for now and organise lots of placements for your year off. You will need a few weeks in clinical practice, and try to get equine and farm as well as small animal. You will also need husbandry placements, such as the lambing already mentioned. A variety is good, so if possible you could explore dairy farming, poultry farming, pig farming, kennel and cattery work (boarding/rescue), and placements in zoos. Things like marine work, lab placements, APHA/DEFRA (not sure if they do pre-uni placements), abattoirs, etc. are more niche but if possible or of interest will help you stand out. I did extra curriculars in the sense of a couple of hobbies but I didn't do EPQ, DofE, or anything, so don't worry too much about these! If you have things you enjoy in your spare time such as reading or going on walks that's also a good way of showing them you have a way to have some downtime away from studying. Best of luck!
