I have seen this information from the official website： Application for the January 2018 intake will open on 1 February 2017.
And deadline is 31 Aug 2017 (Overseas applicants)
So, Is the written and interview time after the application deadline(31 Aug 2017 )? or before?作者: NUS-ISS学院 时间: 2017-3-18 10:54:00
If we receive your application and supporting documents very early, we may do the test and interview before 31 Aug. otherwise, it will be early September.
