(To moderators: not sure if it's the right subforum to post into, but it seems to be the closest. My apologies if it's a wrong one.)
My wife and I want to take advantage of being in a (sorta) Anglophone country with a strong Chinese presence, and learn Chinese at the conversational and eventually business level (both speaking - Mandarin - and writing - Simplified Chinese). We may, of course, use textbooks and whatever language-learning software is available, but it's more fun in groups, the social pressure helps, and socialising will not hurt either. We don't want a private tutor.
The Chinese language schools are everywhere, including right under our condo in Punggol, but 99.999999% of these are for kids.
Looking up in the Internet turned up a couple of results like Yi Mandarin: https://yimandarin.com.sg/courses/ - which seems to be what we're after, but I would like to shop around for options, and ask for the opinion of the forumites. Normally, I'd expect the Confucius Institute to have a program for adults, but I couldn't find any. I also know that Singapore may still be Internet-challenged to some extent, so some of the best bits may be offline.
Location-wise, we prefer either North East or the CBD.
