1.Watch movies in English
Watching series on Netflix might not exactly improve your debating skills or formal register, but it helps you to understand the language better, get used to colloquial, conversational forms of English and implicitly get a feeling for the language. Also, you could try to pick out words that sound highly informal and look up their more scholarly counterparts. Of course, there is also a plethora of documentaries (try anything by David Attenborough to start you off) to be found online as well. Being exposed to a language for the length of a movie might help you to actually start thinking in English.
2. Immerse yourself in English language news
Try to sample a broad range of English language newspapers, including broadsheets as well as magazines and tabloids. As well as helping you keep up to date with current affairs, this range of news sources will also expand your vocabulary. Another advantage is that you will also become more comfortable with how words are spelt and the contexts in which they are used.
3.Start a vocabulary book of useful words
Either in a notebook or on your computer, start making a list of useful words and phrases. Every time you hear or see a word you’re not familiar with, note it down. Don’t only focus on the word itself, but search for synonyms and phrases in which it’s used. After all, you might understand what words such as “precedence” or “tantalizing” mean, but do you know how to use them accurately?
4. Join a conversational English course.
As helpful as listening and reading tasks may be, you also need to use English interactively
and practice your own speaking skills. If you’re lucky, you’ll be friends with a few native speakers who can help you out, but if not then try to meet up with someone else studying English. Another option is to talk to yourself in the mirror or record yourself. Listening to the sound of your own voice might be a little bit awkward at first, but you will be able to hear mistakes of which you weren’t previously aware.
5.Practice, practice, practice
Let’s face it, academic phrases won’t just fall from heaven and straight into your brain. Even if your English is already quite good, don’t be complacent and underestimate stressful factors such as the time pressure in an exam. You still have to practice, no matter how much time you have left before your big day. Try coming up with a word of the day, and then try to employ it as often as possible. If you do this, don’t waste time on extremely specific words you will never actually use. Instead, focus on conversational English which is likely to be relevant in the exam.
