英语不中的话最好请中介,但自己必须对全部过程有个very clear idea. 这样你可以约束中介对你材料的准备程度. 英语不咋地看程度如何,但必须达到及格分(听说读写都要5分or more),否则你给人家理由拒你. 老实说即使雅思考试考到7分,你也需要一段磨合时间去适应native English, since foreigners all speak so fast, and also a veriety of accents is widely used, different style of English is used in different situation, such as daily spoken English, which is colloquial and idiomatic, is very much different from the English used for academic purposes(请原谅写了点英语在这里,有时候自己也觉得好像英语才能更好表达自己的意思).
所以,要想成功,必须攻克英语.要不自己受罪,成功机会也不大.
