What do I have to do first to improve my English using the language material...?

[Twist]

.... I don't know how to use this site to improve my English.
I think my level is elementary. I understand simple messagges, I can talk about myself and use English ... f.e. to buy something, ask for simple information and so on, but I find difficult to understand movies, tv programmes and even conversations and I recognise few words.
I know the basic rules of English grammar. but when I try your multiple choice tests I make a lot of mistakes.

What do I have to do first to improve my English using the language material you suggest?
Please help me!

Twist, constant practice, and understanding the mistakes that you have made.

You appear to have mastered the basics, the rest will come as long as you continue to practice.

If you just have the basic knowledge in English you have a problem...
You have difficulties to understand what people are saying to you. You have difficulties in reading books. I have to chose books for teenagers. I can't read more difficult English. If you happen to fall ill in an English speaking country you risk to die If you can't read the signs at the streets in London you may be killed very soon... You ought to know what "Look right" and "Look left" means. If I go to other places then London I risk to die to because I haven't heard or seen this signs in other cities. If you have difficulties to understand movies in English watch them with subtitles on DVD in English.
