Dear,
Practice daily with a colleague especially speaking, and visit different web site including BBC, aippg, urch, and others. Practice cambridge book 4, 5, 6. Try to read more and more essays. Read Ace the ielts, insight into ielts. For listening module be attentive while listening, use the time properly in reading and memorizing the next questions. Make some notes for yourself for last day quick revision. I think this will help you.
Thanks
