You still aren't thinking outside of the box. Poland has to recognize certificates from all other European countries and you didn't explore how far the certificates you do have get you in other countries.

Not saying you should definitely move, and I remember you said before you don't want to, but there is no reason to put your life on hold for 3 years before of a math test.

And I say that as someone who put his life on hold needlessly for 9, because of lack of resolve, lack of thinking outside of the box, lack of confidence.

I just know there's many Germans here where I study because they found a loophole and avoided the German strictness. Yes, it takes risk and money to live in another country, but it works out for them.
