When you say correct schools, what are you referring to? Eastern Europe? Genuinely interested.
Certainly not the majority of Eastern Europe.
There are many others out there... try to find one the uses modern methods and equipment. Competency based assessment is still in its infancy but many are moving that way. Visit those who you like and ask to see their training material.
Chat with the instructors... the material is only as good as the instructor that delivers it. It’s that relationship that counts as much as the reputation of the school.
Cost should not be the only driver...
