Watch your favourite TV shows in original version. Even if you understand very little, don't worry, this is better than nothing! Try to watch a series that you are familiar with, and see how much you understand. They have english subtitles!
REMEBER, THE BEST WAY TO PRACTICE YOUR ENGLISH IS TO MEET PEOPLE (CLASSMATES, FRIENDS, FOREIGNERS, ETC) AND BE AROUND ENGLISH 24 HOURS. WATCH TV, LISTEN TO THE RADIO, TALK TO PEOPLE AND READ IN ENGLISH. HAVE A GOOD SUMMER!
