Go to the 'additional materials' of this unit and take the suggested test.
You will see you can choose between recording a video and writing text; however, you must share your work in your assignments journal!
Quick hint: think about the characteristics we talked about in the communicative styles unit (ie: how efficient types are decisive and need information in a precise way).
When looking at the test results, think about if they apply to you. And how so?! Make sure you use personal examples to illustrate your opinions to the rest of the community. This exercise is made to help you reflect how you communicate with others: being aware of your own communicative style will help you improve your communication in all contexts, with any audience.
Good luck and remember, have fun!
