Unit 5- Where do you work?

This unit starts with dialogs containing complicated words. After that there is a list of offices in Moscow, which is not so useful if we consider that this is a course for beginners. A lot of words remain unclear and the whole unit is kind of illogically built up. For example I do not get why but they teach numbers here. Something good: there a lot of nice tasks.
It also contains some grammar and a wordlist.
All in all this unit is not too useful either. I am starting to think that I will not learn much from this course unfortunately.
