Polish educational system (especially nation wide maturity exams after high school and college education) are in my opinion decreasing. The maturity exam is getting easier and easier each year to allow more people just to pass. Sure, life is going to verify that somehow, but it also diminish value of this exam.
In my opinion people that are successful in polish school are only those who decide to not follow teaching process given at school but they work very hard on they own, in my opinion the main problem that is present here (and probably worldwide) is students assessment process, every student is taken to the lowest common denominator when it comes giving grades. People that (in scope of the class room) are doing fine, let's say B grade students think they are doing just fine and there are only few things to improve, similarly A students - they generally tends to think they have already reached the peak, when there is still unbelievable much things to learn.
