Sooo, I think this is the right place to ask, so... There is a school of russian on my city, but it costs too much and I don`t want to spend so much money on it, I am just a student.
So, anybody knows if there is annother way of learning russian?

Textbooks & google

Does your school happen to offer an Alternate Language program? My school offers the base languages of Spanish, German, and French, but they also give us the option to take a Rosetta Stone course in whatever language we want after Freshmen year. For example, I'm taking Japanese, but my friend is taking Chinese. If you are unsure, it would be a good idea to ask your guidance counselor, or whoever is in charge of that kind of thing at your school if they offer this program, because the more exotic languages definitely look better on a college application.

Check the website of the Russian embassy/consulate, they might provide infos about institutes/associations teaching Russian that are not expensive.

Or look for any association in your town, or contact someone from a "Russian loving" circle.
