Hey! Just wondering when it would be a good time to start visiting vet school open days? I will be starting year 12 in September
I think the youngest person I met at an open day (not vet school though) was in year 11 and it went up to mature students who have taken a break from studying. You can either go this summer (you may be too late, though, for the summer ones as they could be booked up but give it a try) or there's often ones in September-November for those who couldn't attend summer open days.
However, most students go in the summer after finishing year 12 before starting year 13 so don't worry if you don't get chance to go this year.
I once met a year 10 at an open day, and although this is very organised I would argue that going so early is of limited use since universities can change a lot in a small amount of time.
I personally didn't go to any until the end of year 12, which I think is the ideal time
