I am glad to see you on course for business. Before you start the course let me suggest to you an instruction on how to make this course more successful.
Before any text you will find a small vocabulary. Please, check it out and translate to your native language. Read the text and lesson the audio file next to it. If you become tired - please, rest. If you have no time to read - please, download audio and just listen to it as many times as you can and read and translate it later.
Every grammar rule has its own explanation, several examples, and practice (exercises and text with audio). Learn all of them.
I also added some videos for you.Please, watch it, try to answer the questions below and then try to make your own presentation about yourself or about your company.
