The importance of English
Although only the third most-spoken language in the world, after Mandarin Chinese and Spanish, English is probably most used as a second language. It is estimated that around a third of the world speak some English.
Learning in England versus learning in your native country
For those who are looking to better their English for career purposes, you may be tempted to take classes in your own country. Although this is certainly cheaper and more feasible with a working lifestyle, if you do get the opportunity to take classes in an English-speaking country then you should take it. Nobody can teach the English language as well as a professionally trained English native.
By living the UK, students are surrounded by the language at all times and are practically forced into speaking English. Everywhere you turn and everything you do, including shopping, public transport and the media, you must use English. Instead of switching off until your next lesson, which can be the case when studying in your own country, your brain will be switched on to English at all times.
Schools in the UK
The location can make or break your trip to the UK, so it is worth thinking about what you really want from your trip. If you are want to get down and do some serious studying for an exam or foundation programme UK schools in the countryside, where it is much more peaceful and quiet, might be more suitable. But if you want to experience the social side of living in the UK, a school in a major city, such as London or Manchester, might be more appropriate.
