I don't know who manage this website, this is very sad that they don't know how to answer the questions. When I uploade questions without the case study. First they answered 4 of them out of 7 then I uploaded rest 3 then they said they need the case file so my point is how you answered 4 question without file in first time, either you don't know how to answer or you don't want me to get all question answer, this is your business, first get students then do half work and say upload file. Yesterday I uploaded whole file and seven questions and now my whole post is disappeared, this is crazy just because you guys don't know how to answer the questions that's why you vanished my whole post, ridiculous.
