What kind of field would you peruse?
In general, Croatian schools are good but not perfect. The best thing is that the education is free, even your first enrollment in university. In some places, even elementary and high school textbooks are free since they're being inherited from the former, older generation. At university, most literature can be found and borrowed at the library. With a student card you can eat cheap in student restaurants (about a dollar for a whole meal) and you can also get lots of other discounts on movie or theater tickets, for example. Via a special agency you can easily find and apply for a student job. And you can study almost anything here, but not in all cities (keep that in mind when applying). There are also scholarships available for students with low income, physical disabilities or extraordinarily good grades. Most students stay in student homes where they share a room with a roommate.
The biggest downsides of the Croatian education system is that it's very theory-oriented and not as practical, but that also depends on the field you're studying. At university you also need to pay if you achieve less that 55 ECTS a year (points that you gain by passing exams). But for each exam you have four opportunities per year (and eight in total) and you can take the exam in either September, February or June/July.
