A really solid tool – L-Lingo Learn Vietnamese Review

This is a really amazing tool for learning a very difficult language. It only introduces a few words at a time and adds to your grammar slowly, but over the course of the lessons you can definitely sense progress. I have a few small issues: 1) occasionally the program will have to use a word it hasn't actually taught you. I suspect this is because that word is necessary in Vietnamese but not, for instance, in French or other languages L-Lingo teaches. But it is very confusing. 2) some lessons have a very limited number of test sentences, so you always get the same "five bottles are on the table" or "the boss is standing in the office." A few more sentences to choose from in each lesson would help.
