Well since nobody posted here yet, I'm going to make a topic for people to post their advice on how to learn Russian in. I'm currently teaching my friend Russian, it's going quite well, and in a few months you might expect him on these forums. Anyway, an advice for today:
When you try to memorize Russian vocab, read it carefully. It's much easier to memorize visually rather than by sound.
It's a simple advice, but it's funny how many people don't follow it and therefore mess up a lot.
