Vocabulary is the most common barrier to learning a language, and most often makes people give up even before it actually starts. In fact, the main key to proficient foreign language is to get closer to the words that are familiar and often used in everyday conversation. Find out what vocabulary and phrases most commonly used by people when talking – move them into your own notes or use apps, such as the Anki app you can download – and learn regularly with a gradually increasing repetition strategy (once a day, every other day, four, eight, etc.). Meanwhile, you may check out the Trinity college Glasgow if you want to take the test for acquiring the UK visa.
Or, you can use your favorite reading book as a child (which you understand deeply about the storyline) – Snow White or Pinocchio, for example – in versions of the languages you study as well as your mother tongue (for example, the English, German, and French).
This will allow you to translate foreign languages line by line and easily describe how sentences and grammar of a language are built.
