Small group Vietnamese language classes Dec-January?

Hi,

I will be in HCMC for around 6 weeks from December to January. I am interested in knowing if there are any group (preferably small group) language classes I could take during that time?

Someone here linked VNU HCMC in another thread for language classes but the link was broken. When I found my way to their English language page I didn't see too much information but I think the shortest classes were 8 weeks.

I guess what I would like to find would be a language school that has open entry/open exit classes where they would put you in with a group of people that are roughly on your level and it would be like a conversation class.

I think an immersion class that is several hours per day but which requires little study outside of class (other than trying to use what you learn while out and about) would be the ideal situation for me but I'll take what I can get based on what is available, what I can afford and what fits in with my schedule (which is pretty open right now but I may consider taking a TEFL?TESOL type class while there as well).

Anyways if anyone knows about language schools that offer these types of small group classes in HCMC please let me know.

Thanks!
