Would you like to enroll US or UK education system for your child?

I would be fine with either, depending on the quality of the schools that are offering it. And it also depends on the kid. There are a variety of choices of curricula and education philosophies in both countries. If we are talking about Singapore, my top choices - for different reasons, of English language schools, were St Josephs International (IPC, IB), SAS, and UWC (IB) when I last researched international schools in detail about five years or so ago.
