Be careful aiming for lots of new words. It is usually better to review the words you already know and make sure you use them correctly. You should aim for accuracy when you use language, rather than aiming to impress. Each word you use incorrectly will lower your IELTS score, so limit yourself and do not try to learn it all. Be strategic in how you approach IELTS. Build on your strengths and be careful of the areas where you struggle.
Actually to increase your knowledge of a language takes time – there is no quick fix. To enlarge your English, you can read Al Jazeera news, BBC news, online magazines etc. See the useful pages of this website ieltsscore.com
