Verinica, did you end up signing your kids to Nexus? And if yes, what is your impression and what are your thoughts about the school.
I went there in May and was impressed.
I'm answering the question the OP asked on what is the difference between the schools. No offense intended unless it's offensive to have international schools in Singapore who employ foreign teachers. What grades/subjects are the local teachers teaching at Chatsworth, ISS and OFS? cant gibe you any...
