The training vocabulary
As a beginner, instructions will be given to you in an easy-to-understand manner. However, as your training progresses you will start to hear various japanese words which are basically instructions telling you what to do. Additionally, you'll also hear a variety of phrases that are used to describe certain things. It's a good idea to get used to this. That way, over time, just a few words or even a single phrase from the class instructor will be all that you need to tell you what you should be doing next.
