There are no specific tasks you must do before you arrive. However, you might find these suggestions very helpful.
Reading
Research and experience shows us that one of the best things you can do both for your English language in general, and for your academic English in particular, is read, read and read! Try to get into the habit of reading English regularly: if possible longer texts, not just short webpage material (whole news articles in major newspapers or news magazines are a good start). If you can, choose items related to your academic subject. It is fine to start with something relatively easy, such as basic textbooks, if this gets you into reading. You need to do a lot of reading at university, so it is best to develop a habit now.
Listening
You will, of course, be listening to English all the time when you arrive in Britain. If you are not used to listening to English, or even to English in a UK environment, you can start to practise now. Good places to start are:
Writing
As well as reading and listening regularly, try to write frequently in English even if you just write a diary or your thoughts about something you have read or heard. Writing English, a little and often, will help you become more fluent. We will help you improve your writing but you must get used to writing English first.
Get used to using a standard English-English dictionary. We suggest using Cambridge English Dictionary. It has British and American English, pronunciation recordings, and also includes translations into other languages as well as links to a thesaurus.
