Make lists of words you learned and categorize them, e.g words you use at the office , words you use at school , greetings etc.. - Keep a diary in that language. Try to use the new words you learned to write and compose simple sentences .The more you add up to your vocabulary, the more you can form intricate ones. Test your level!. -Take a holiday abroad if you can afford in countries speaking the language you are learning. It is an opportunity to practice with natives and learn more about the culture and people.You can sign up in language courses in those countries as well beside visiting its historical and monumental buildings and museums . You will be using guiding phrasebooks to help you get along there. The whole process will help you learn more words, expressions and practice speaking. All the above can help you improve your language. Intensifying your efforts will make you improve faster. Concentrating on whatever method you are applying will guarantee you a more steady improvement. I hope those tips were helpful. Good luck:)

Hello Ali, I will give you some advices and tips to learn languages. The time you need to improve depends on how much time you dedicate to learning and how intensive your effort is. -To start learning any language from the scratch you might need to take some initial classes to learn the alphabet , how to pronounce ,basic vocabulary and grammar. You can do that by taking classes in a language institute or by self learning online, although some guiding from a tutor at that early stage is recommended, unless you are able to depend only on audio/video facilities. - Then you have to practice and increase your vocabulary through different means such as : *Reading at your level of comprehension simple texts or books and looking up new words . * Listening to the target language through music and possibly reading the lyrics . * Watching movies in that language with subtitles in your mother tongue. * Chatting with natives online using voice chats or in real life .Mingling with natives is a very good way to be constantly listening to speech in that language, even if you don't understand at the beginning.

Bonjour Ali. This is my advice as an English teacher. I think that in order to learn English well, it is very important that you listen to and practise spoken English as often as possible to improve your English pronunciation. You can also click onto Language Partners and Language Teachers at the top of this page and email native speakers to set up a time to practise oral English. Click onto Groups and join one that you like to practise your pronunciation. These sites are also good for listening and pronunciation practice that Italki members recommend. http://www.bbc.co.uk/radio4/

Only by studying things like grammar and vocabulary and doing exercises, can you really improve your knowledge of any language. Many people think that exercises and tests aren't much fun. However, by completing exercises and taking tests you can really improve your English. One of the best reasons for doing lots of exercises and tests is that they give you a benchmark to compare your future results with. Often, it is by comparing your score on a test you took yesterday with one you took a month or six months ago that you realize just how much you have learned. If you never test yourself, you will never know how much you are progressing. Start now by doing some of the many exercises and tests on this site, and return in a few days to see what you've learned. Keep doing this and you really will make some progress with English. Nobody likes to hear their own voice on tape but like tests, it is good to compare your tapes from time to time. You may be so impressed with the progress you are making that you may not mind the sound of your voice as much.
