go for the best your family can comfortably afford. so out of this list, probably cambridge? how about considering a scholarship from singapore, or looking into colleague grants/scholarships with no bonds to help with expenses as well?
having gone through school in europe and university in singapore, i would say the latter did very little for me. the overall academic and learning environment is not ideal.
i was accepted into a couple of top UK universities but my parents were far from being to afford it at the time (asian financial, dot com crises) and i am not a scholarship type (the bond alone makes me feel sick)
education should not just be about getting a good job in the future; it's the whole experience of living and learning--and learning to THINK most of all--which in turn could get you a great job
of course if you just want a good/stable job, i guess
NTU accountancy type of local courses are okay too
