How to apply for national university of singapore?

First thing, you apply direct on the NUS website. They have their own online application portal, not like UCAS for unis here. Basically, you'll need your A-Level results, or your predicted grades if you're still studying. You also write a personal essay, a bit like a personal statement. Make sure you look at the entry requirements for your course. Some need specific subjects. There's an application fee to pay too. After you submit everything, you just wait. The deadline is normally around March, so get it sorted soon! Good luck with it.
