IELTS is a test for non-native English speakers. Why did you have to take it?

It's often required for immigration purposes. Countries/Universities will let you off where you're coming from a country that has english as it's main language or have studied a degree in the language, but they often won't if you're a native English speaker living elsewhere.

Singapore is a “native” English speaking country yet has an extremely distinctive accent.

(usually seen as a negative by both Singaporeans and non-Singaporeans)

I had a 3-month stay in Singapore (at CQT, NUS).

The first two days were a shock, as I felt it was a different language. But just after some time, god adjusted. And I find endearing both Singlish pronunciation and phrases.

For example, the first time I hear "ondah-cah?" I was puzzled. Then understood that it is "Monday can?". Which, as I learned, means "Would Monday work for you?".

Migration purposes. I'm from South Africa, so it was required.

I would have done it regardless, because it got me extra points.
