坐在马桶上翻看发下的那本报名指南，发现个有趣的报名与身份的问题。由来如此：
A pupil with better rounded aggregate score will be considered for admission first, subject to the availability of vacancies in the selected school. If there is no more vacancy, then the pupil will be considered for his/her next choice school(s).
In situations where there are two or more pupils with the same rounded aggregate score vying for the last place in a school, they will be posted based on their citizenship status (i.e. Singapore Citizens, then Singapore Permanent Residents, then International Students). If there is still a tie, say between two Singapore citizens, the one with the higher unrounded aggregate score will be posted into the school first. If there is still a tie between two citizens with the same unrounded aggregate score, then posting into the school will be determined by a computerised ballot where each candidate is given an equal opportunity.
据此，整数分数的学生只有到了最后一个名额时，才有小数点的问题，也才有身份的倾向。可是，如果分数线在250的学校，当安排了所有251的学生之后，还剩下不止一个名额（LAST PLACE)的时候，又是如何排序的呢？假设20个名额，可全国还有100个250还没开始参与电脑排序。
如果是按小数点排序，那么和MOE的第一段叙述不符合：“Pupils are posted to secondary schools based on merit first according to their PSLE aggregate scores rounded to the nearest whole number. ”（http://www.moe.gov.sg/education/ ... hool-posting-phase/）按姓氏字母？学号？
如果是按身份，以往有没有同一整数分，报同一第一志愿，反身份序列的例子呢？所谓的INTERNATINAL STUEDENTS又是按照什么序列呢？
