Hi Bernouli, for all your questions there's answer, it would be nice if U can be more precise what you want ,than someone can post exactly some known info ...
For example , there's several ATO / Schools in Hungary to obtain pilot license ,and of course prices vary . But more or less price does not play so much roll if you search for specific option suitable for you. Let's start with ATPL Theory , more or less price is the same between schools, but, do you want classic room classes or online classes with self study ?
