All About Britain’s Teenagers

School
British teenagers can leave school at sixteen after taking their GCSE exams. They study for exams in as many as ten subjects, so they have to work very hard! Today’s teens spend more time doing their homework than any teenagers in the past, studying for two and a half or three hours every evening.

Free Time
It’s not all work, of course. What do British teenagers do to have fun? They love watching TV, going out, meeting friends in Internet cafes and listening to music. Researchers found that 99% of teenagers questioned in a survey said their favourite activity was watching TV, while 98% also liked listening to music. Some teens like UK rock music, but others prefer to listen to hip-hop or nu-metal on their i-pods and mp3 players, 89% spend most of their free time online, e-mailing their mates or making new friends in their favourite social networks.

Technology
As well as the Internet, teenagers in Britain use their computers to play games and do their homework. They also love their mobile phones and spend hours texting their friends and chatting. Today, phones are getting smaller and lighter and you can do a lot more with them than just talk. Text messaging has become the coolest and trendiest way to socialize. More than 90% of 12-to 16-year-olds have a mobile and experts say that this trend stops teens from spending their cash on sweets and cigarettes. The latest craze, mobile phones with built-in video cameras, is taking the country by storm, as are digital cameras with which you can take photos that can be sent over the Internet.

Fashion
At school almost all British teenagers have to wear a school uniform. However in their free time they can wear whatever they like and what they like is designer labels. In fact, 40% of British teens say that they think it is important to have the latest designer clothes. Nike , Diesel and Paul Smith are the top favourites, but looking good doesn’t come cheap in Britain and many teenagers think nothing of spending over £100 on one item of clothing.
