(1) My advise to future and currently students is to best focus on all the course units. and importantly to write down notes as they progress to the next units. I would further advise to read the summary at the end of each course unit. I have found it to be helpful.
(2) customer service work place. I found this unit to be interesting because I found it to be the foundation phase of this course .
(3) this course has been informative and empowering to me . I look forward recommend it to friends .
