Mongolia continues to adhere to the Soviet model of 10 years of school education of which 8 are compulsory, although this is being gradually extended in the direction of the European model.
In 1989 when communism was starting to fall elsewhere, many Mongolian weren't really ready for the change.
There are over 4,000 rivers in Mongolia, known as Gols in Mongolian. Most of the country's 20 or so significant waterways are in the Northern Arctic Basin in Central and Northern Mongolia, which has the highest annual precipitation.
