as someone currently learning Vietnamese do you have any tips for learning the language? I've learnt some Mandarin so I am no stranger to tones - but the tones in Vietnamese seem quite different.

I've been using Pimsleur which I highly recommend, but I find I end up atuned to their particular voices and can not understand genuine Vietnamese speech. Also I am using memrise to learn vocabulary, but without example sentences and the like I find it of limited use until I find the same word in a real life context.

Interested in your thoughts.
