Hi! I like to see how my pupils grow! I like to help others to learn a foreign language because I went through this me too.
In 2015
I tought French as a foreign language before:-)
It is difficult in the beginning, because of cyrillic alphabet and cases.
To match possessive adjectives/pronouns with nouns (in case and number)
Patience and curiosity.
When you do not practise to speak Russian, it is hard!
Any language is actually a music! Try to catch some particularities of Russian intonation, don't think too much about sens. Others will understand your Russian better!
Go to Russia, live in a Russian family and learn with Russian teachers/
It depends of a level/a person.
