个人建议：去charter, 读在职Phd, 比直接读要划算。My Analysis: 1) There is a good environment in Charter to pursue Phd; 2) You can get more experience from industry, although, NUS have so much money to buy advanced euipment, but, it still can not compare with Charter, 3) You can earn both money and working experience, during the phd program. maybe, you can try.
