exercise of the language
what time is it for exercise of the language? and with ? who?
Well, if you take it seriously, like write on paper and memorize new words to enrich your vocabulary, 3 months you'll be able to communicate with people pretty well.
But answering your question, I believe that the period you need to master a language would be one year. Especially if you live in that country.
However, allow me to correct your question: How long does it take to master English?
Your English is not bad by the way. Keep it up :-)
Yes, you are helpful. or Yes, you are great. *
Usually "grateful" is used to describe yourself not others, so you say: I am grateful!
Unless you KNOW someone is grateful for something someone did.
بتحبي أشرح بالعربي, أو مفهوم هيك؟
