推選答案以下原文摘自NUS官網，NTU官網上也有類似言語：
The University has not engaged any external agencies to undertake graduate student recruitment on its behalf. Candidates interested in our graduate programmes are advised to apply directly to the University and not through any agents. Candidates who apply through agents will not have any added advantage in gaining admission and the University reserves the right to reject such applications without giving reasons.
如果你英文不差的話應該明白什么意思吧：
申請者需要自己申請...通過中介申請也不會有任何好處...學?？梢詿o理由拒絕這樣的申請者...
愿意冒險找中介的話也隨你，反正我覺得沒什么必要。其實拿自己的成績上網申請就是了，整個步驟非常容易并不繁瑣，而且申請費也很便宜。

對于申請者的最低要求在官網上也寫得很明白。不過有些條件不會明說，比如211/985之類的。學校不好也可以申請，只不過幾乎沒機會錄取而已。


還有問題的話歡迎追問
