Yeah, Warsaw has a dedicated international program which has an annual intake of up to 50-60 students, and which is taught solely in English. Students come from Sweden, Norway, Finland, Ireland, UK, France, Spain - too many countries to mention!
Brno and Budapest's international programs have been established for a while, so I know they're decent enough. But be wary about Wroclaw - I've heard bad things about the way their international program is run.
Well, with regards to applying, it's entirely your choice. It all depends on how you feel about these 2 things:
- How much you want to go to these other universities
- How soon you want to start training to become a veterinarian - if the answer to this one is "sooner rather than later" - apply to Warsaw now.
Warsaw is a decent uni, and living in a capital has its upsides - for example, thanks to being a capital city, there are lots of things to do, and the standard of living is really good. I went to the 17 mai celebrations at the Norwegian Embassy this year - you wouldn't be able to do that in Brno or Wroclaw!
Also - if you apply to Warsaw now, take the entrance exam and get offered a place - but then decide you would rather try for the other unis - then I'm sure you can defer the Warsaw offer until next year. That way, you have a vet offer but you also have the opportunity to apply to other places.
Obviously don't decide to defer only 3-4 weeks before the course starts, and make sure you have a solid reason so you're not messing the Dean's Office around.
I would highly suggest researching information about all of these universities and the cities they're located in - if you haven't already done so. Moving and studying abroad is exciting - but it is not something you should do on a whim.
Hope you don't mind me asking - where are you from?
