/ I have a "zero" chance to succeed in Poland - I do not have a degree!
What I gathered is the letters before your name are an offensive weapon dealing with people outside your family. You could call it down right irresponsible but actually my 3 kids have been in primary schools in 4 different countries: Canada, US, England and Poland. Luckily they are multilingual,extrovert and did o.k. in all. It gave me an excellent insight into how these countries schools compare:
Schools in England- children and teachers very friendly, good equipment, level of teaching fairly good, project based, most emphasis on team work, little homework, plenty of encouragement and less competition in the class. Teachers appreciate feedback and help from parents.
Canada - all the above but lower expected level to pass.
Poland - more rough treatment of children, teachers can get away with short temper/ sarcastic comments in the classroom. The level is cranked up by fear and memorizing a lot of material. Parents are expected to teach at home helping with homework (lots of)
very little is project based. There is strong rivalry among children and "friendly" is not easy to find.
US - feedback from parents is not encouraged. The expected level seems higher than in England. All project/problem based work in classroom. Almost no memorizing except in geography or languages. Lots of homework exercise in major subjects. More competitive than England. Very tight regime of rules of what is, or is not allowed. Friendly: better than Poland worse than England/ Canada.
