Hey, Happy Chinese New Year everyone although most may not be Chinese haha. I am a newbie here.

Hope to get some useful advices for my university application chores haha. My problem here is I have been offered a Business program by NUS and I have been wanting to pursue a Finance career. And the deadline to make my decision is just 2 weeks from now. Well, I applied for HKU, HKUST and CUHK for the Quantitative Finance program, but they are not giving me any notification yet up to this moment. Regarding to the previous posts, it sounds like HK universities are more likely to give late offers. So what are my options here?
Well, I have thought of sending a mail to NUS for a postponement of the deadline and tell the HK unis I have already received an offer. But if I am so unlucky to be informed by the HK unis as late as around July and August, I just don't seem to believe NUS will wait for me that long.
Do provide me any constructive advice. Sigh. =)
