1. 复议需要向你报名考试的考试中心提出申请。需要写封申请信(要亲笔签名)，你的成绩单和复议费。你可以要求四部份全部复议，也可以只要求单项。我是在澳洲考试的，这儿的费用是:L and R 15 AU$ each, W and S 40 AU$ each. 2. 复议必须在接到成绩单4周内提出。 3. 复议历时1个月左右。 4. 复议成绩不会降低。如果复议成绩比原来的低，考试中心还会给你原来成绩。 5. 复议是终审裁决，不能再要求复议。 我觉得复议对作文和口语有用。听力和阅读为客观题，因此用处不大。作文和口语得分和阅卷人主观因素有很大关系。作文和口语没有半分，如果你得分在5和6之间，有人可能给你5，换个判官就可能给你6。复议的判官和原来的不同，因此你很有机会提高分数。为了提高分数，可以在申请信里下点功夫。我也不知道我的申请信是不是好，起不起作用，我把它附在下面给大家作个参考吧。
Dear Sir, My name is XXX. I took part in the IELTS test(General training) on 25th May in your cenetr for the purpose of immigration. 0227 is my candidate number. I am writting to apply for the reassessment of my test results. As a pre-requisites of profession assessment, I need to take a IELTS test and reach at least level 6 on all four components. However, my writting is only at level 5. I have been in Australia for one year and have published several papers in English. I think my English writting should have reached at level 6. My poor score of writting maybe is due to my poor handwritting on the test paper. I will have lots of trouble if I wait for three month for the next test. Therefore, I want my writing part to be remarked. Enclosed are my original test results and payment for this application. Anyhelp from you will greatly be appreciated. Regards. XXX
