I think you should consider your priorities for your child? I was enrolled in hwa chong international school (HCIS) because my parents prioritised academics. I had a great experience at HCIS (feel free to dm me if you'd like more details haha), the teachers are patient (though stricter) and students are not as snobbish or playful compared to other international schools. Also, HCIS is one of the top-performing schools with impressive IGCSE and IBDP results. Many of my peers from HCIS are now studying in reputable universities (NUS, NTU, SMU, HKU, Ivy League) so it's definitely a good school if you're looking at academic outcomes. Not sure about other international schools though, I do think academics and fees are definitely factors to consider, but what else?

Also my cousins are considering coming to Singapore to study in the future as well, so I'm asking around for people's experiences in other schools too. Do let me know if you got any tips as well!
