Dear cac ban,
There are quite a few threads in the forum talking about learning Swedish, it seems like you are all really interested in Swedish language. just a recommendation for you who live in HCMC, one of my Swedish friends is actually coming back to Vietnam to live in HCMC and he is actually keen on teaching Swedish.

I think it would not be a problem for 4 or 5 of you to share the cost per class. Learning a foreign language is actually pretty fun, it is also interesting to communicate with the Swedes in Swedish, and most practically to many international students I know here, it seems more likely to have a better chance to get a part time job if you speak Swedish ( just a little bit in some cases).
I think this is such an experience to share and I hope this helps
