We had equal opportunities to do well, regardless of whether we were from rich, middle-income or poor families – essentially because, from what I could see, teaching was benchmarked on the median performer in class. And at that time, there was not much difference between the median and mean because the socio-economic disparity was not significant. And the clear emphasis on merit – where the best performer, regardless of his background, would be rewarded – gave parents from the lower-income segment of society enough incentive to push and motivate their children to do their best and have a crack at success in life. And for us, the pupils – because we saw fairly immediate results of hard work, we were motivated to continue working hard. As such, top schools like Raffles Institution (RI) and Raffles Girls' Secondary School (RGS) – which had the pick of the top 2% of each cohort – had a significant proportion of students coming from families in the lower-income segment of society. Many of these students, such as Mr Lee Kuan Yew, Mr Goh Chok Tong, Prof. S. Jayakumar, went on to lead the country. In fact, many of us of the right vintage would be familiar with the line, "RI ruled the country, and ACS owned it", because unlike in RI and RGS, students from ACS tended to come from families that were financially and socially well-heeled!
