Where to go after high school?

After graduating, I definitely want to go to university. However, I am not certain about a specific job I would like to do in the future. I can imagine myself in an IT sphere. Part of me wants to study in Slovakia but other countries also sound great. As I wrote in the "About me" part, I like photography and gardening but those are not the areas I would like to work full time in. After obtaining a university degree, I want to stay in Slovakia.
