Vet School is a culture shock for most UK students. Think A-levels took 2 years. You might cover the equivalent in 6 lectures. Yes be exam focussed- they are designed to let you know what you dont know and are a sampling exercise, but you need to realise that this is a 4 year project (final year is easy), where you have to quickly adapt to not been told every day that you are wonderful and a great pupil. You are now considered an adult and that means working very hard (cf the typical Arts or Science student who just pik their noses), being reflective and picking up clinical, motor and interpersonal skills.
At the same time compared to other courses, you join a family and you will find staff generally only too helpful. First name terms are the norm at most schools (except Cambridge where genuflection is mandatory).
