Who cares abt the sec school? Tell your mom to get her head out of the toilet bowl.
Most of the RI and ACS boys..end up in some shitty university locally eg NUS, NTU, SMU, together with the rest of the non RI and non ACS boys, together with people from Bukit Panjang Govt High and Changkat Changi Sec school studying alongside with them and taking the SBS bus from Clementi bus interchange, leading unglam lives, living in the smelly hostels and studying in the rundown universities and spending their weekends in some lame club in clark quay like zirca or dunno what shit dolly.
Look for the university credentials (WHICH university) and the address of his parents in Singapore as the gauge.
RI? ACS? Secondary school?!? All you need is just to get the PSLE scores to get in. I know ACS boys to live in HDB flats btw. So don't think every one of them are scions of some empire. What a bunch of morons both your mom and you are.
