I wouldn't say that our English pronunciation is strange. It's just not
American or British-accented English, although I would say that we
do have
a tendency towards British English due to its predominance in our
schools. If you would like to improve your written English, Singapore
is a fine place to start; spoken English, not so much.
But anyway, thanks for that bit about the nations which supposedly have
English as a first language - I was wondering if I needed to take the
TOEFL for entry to an American college.
