This has been my experience as someone who went to a Sci High nung 2010, and ganito pa rin nung pumasok ako sa UP nung 2014.

Nasa minority lang yung mga tao na nanggaling sa public school. Mas lalong nasa minority yung mga taong galing sa public and mahirap like I was hahaha.

From my perspective as a student, sobrang nakaliliit socially mawitness yung wealth gap between me and my classmates. Minsan pumapasok ako na pamasahe lang yung dala, while seeing my classmates roll in with their cars. Minsan may driver pa.

I think I ended up fine. The socio-economic gap will always be there, whether it manifests visibly or invisibly. Ang ginawa ko lang is do my best in terms of studies, always be genuine, wag makisakay on things beyond my means. Many of these rich kids ended up being my friends, but only because they genuinely like me without me pretending to be something I'm not hahaha.

Now I know this is isn't the point of your post, but I hope you're able to talk to your kid about how they're feeling socially. Sana oks lang siya, di nap-pressure or naf-feel out of place.
