about 溫習ielts 的問題

If your English is above intermediate level(ie.CE Eng(Syll.B)=C/new CE Eng Syll=5/UE=E) , I suggest you do the mock papers first(IELTS 3-6, 1-2 is too simple, they're useless(the books are made by Cambridge)).The IELTS mock papers from Mainland China copy version are cheaper.But please remind that other mock papers made by China(not Taiwan) are very simple, especially the listening part, so please do not do these useless mock paper.
If your English is not that good, then you should take some courses to upgrade your English ability first~^^~
I recommend you to have some individual lessons before sitting the examination so that you can practise more as it is not that easy to get high score(>6) in writing paper and speaking paper. I myself got very low score in these 2 paper, so the overall band is not good. I have many friends who got D in UE, but they also got only 5-5.5 in these papers!! I wanna remind you, if you sit the IELTS repeatedly within 2 years, it will show on your IELTS report. Thus, it is not good for you!
The remaining papers are easy, you can practise them by doing the mock papers
Good luck.
