Just want to sing Genki's praises!
At my university it is the course textbook and it (aswell as my excellent teachers of course) has helped go from being a noob at Japanese to an Intermediate speaker in just 2 and a half years.... (I only call myself intermediate because the uni paper I'm doing at the moment is titled "Intermediate Japanese".. but what I'm trying to say is that I feel my progress has been significant)
