Having studied in Russia, Germany and UK, I would say that:

- Technical education was emphasized over humanities. It was much more important to produce good engineers as required by industry and military rather than "thinkers".

- Maths was traditionally well taught across the board, whereas in Europe and especially UK it is seen as tough and unnecessary.

- Doing well in school is seen as a point of pride. Thus many work hard to do well in school to get the respect of their peers.
