As you can see on the table the different countries have many similarities, but many differences too.
For example every country have math, physics, chemistry, biology… so science subjects are learned in every country. A big difference are the different languages of course, every country have to learn their own language and English. But the second languages are very different. The German have French, Spanish, Russian, Latin as a second language, while the polish have German, in Slovakia you can choose between Russian and German, in Macedonia they speak French and in the Czech Republic you have to learn German too!
