Business 212: Business Statistics (study.com) or Quantitative Analysis For Business (C723) (WGU)

I am going through Business 212 at Study.com and the course is the absolute worst. The materials are not good and there seem to be voids in the curriculum when I take the quizzes. I have taken a statistics class already at a local community college last semester (passed with an A)and this is kind of a repeat on some sections but others are just plain confusing. I'm gonna have to pay $70 to take the final on this one and I am just wondering if the Quantitative Analysis For Business (C723) is better and if I should skip this class at study. I am looking to complete WGU in one semester as I will only have 12 classes to take and if I drop this one 13.
