Here are some
http://www.dcielts.com/?p=1297 that I do
not recommend for IELTS exam day.SpeakingAlways give a long answer and keep on speaking until the examiner stops you. This will only make you incoherent.
ReadingNever spend more than one and a half minutes on any question. Not all the questions are equal. There are a variety of timing strategies possible and it can make sense to spend longer on some questions than others.
WritingGive yourself as much time to write as possible and only spend 1-2 minutes planning. If you plan well, you will write more quickly and more accurately. Think 10 minutes, not 2 minutes.
ListeningConcentrate on key words in the question. You don't know what the key words are until you have listened. Concentrate on the whole question and what it means.
