I am on the same assignment as well. It is a little hard to wrap my head on starting this assignment. I found an article on forbes regarding the AIDA formula that I found somewhat helpful. Hope this helps!
I just submitted unit A and my tutor is also Alexandra Slawek. I havent gotten my grade back yet but i am so excited that someone has actually worked with her and really likes her. I am looking forward to my feedback! BTW, good luck
