One aditional factor you may need to investigate - with no APs could she even get admitted? The Slovak school system and final maturita exam is accepted by UK universities as equivalent to A levels, whereas they want APs for Americans.
This college in Bratislava which offers an American style liberal arts degree for 4K (in euros) says they assess academic ability of non-EU applicants on "the results of secondary education and the results of the leaving exams." (Even if your daughter is a Slovak citizen, her education is not in the Slovak citizen so I'm sure she would be assessed as as an international.) http://www.bisla.sk/criteria-for-admission-for-2017/2018
