1. Which university is more recognized in the European Union?
Any university, I guess. So £ódź.
2. Which of the university would have a cheaper cost of living? My friend said that the cost of living in Nowy Sacz in around 1000 PLN per month(accommodation, food, utilities)
I guess £ódź would be more expensive because it's a big city.
3. Which university has a good business program?
Szkoła Główna Handlowa in Warsaw ;-)
4. What are the job prospects for both universities outside Poland?
No idea, but surely Uni of £ódż has bigger ones.
BTW, I study at Uni of £ódź.
