DO NOT WASTE YOUR TIME WITH THIS COURSE.
I concur with Brian O's assessment. He is 100% right with his comments about what is needed. I have all of that and more (S.T.E.M. courses out my ears, grad and undergrad) and have successfully completed six other quantitative courses from Coursera. It is sloppy and unprofessional beyond belief. Terms are not defined, quizzes are confusing and you will spend most of your time trying to figure out what is being asked. It's not worth your time, let alone the $79 for a cert. In addition, most of what he does in Excel is much better done in R or JMP or any of the other packages out there.
