A good, useful course that not only helps you acquire new vocabulary but also explores some technical aspects of business negotiations. However, it's worth noting that some of the course's steps are quite complex and specific, and impossible to solve without knowing the correct answer: Lesson 1.3, Step 5 Lesson 1.5, Step 6 Lesson 2.3, Step 5 Lesson 2.5, Step 6 Some of these steps were completely impossible for any student to complete. Therefore, I would recommend/request the author to add hints or answers or remove these steps.
