Do you mind sharing more information? What school was this?

Here's the book on math teaching lessons, and although it's in Russian, you can get an overall idea of the level of math involved by skipping through the pages: http://www.mccme.ru/free-books/57/davidovich.pdf

It describes a 4-year program, from 8 to 11 grade of russian school, for kids from 13-14 to 16-17 years old respectively.

Thanks! I'm very interested in this approach and will take a look. Wish I could find something like it in English, as I don't speak Russian :)

Sure. Here's the website, but it looks the same as ten years ago, so I doubt it has the latest updates: http://sch57.msk.ru/index.en.html
