Final year is split into blocks so you do two weeks of lectures and then a six week block of practicals in Horses, Ruminants, Smalls and Pigs. All the practicals must be completed at uni as it's what will be examined but you also have to do some placements at home and can be at specialist clinics according to your interests.
I think at Budapest they have a whole semester of placements which is when they can do them elsewhere.
After summer of 4th year you need to see practice at home, most people go beyond the minimum which is currently 2 weeks. I try and see practice every time I'm home and usually do about 9 weeks.
