be careful with “teach yourself” books and cd's. they usually have too much English. you need things with repetition of the Vietnamese. most of them are less than useful and you waste your money. most of the stuff on you tube involves pretty girls telling you about Vietnamese language. they have a different dress on every chapter and look very nice but they do not understand language acquisition. if you find anything better, please let me know and I will post it here. btw – I speak more than basic, I am just trying to be helpful.
to be ignored: “be where you want to be” and “pimsler” cd's but there are many more, including on you tube, that are not useful.
