I have a question (possibly a silly one) about how adcomms view courses taken by the students online (Coursera). I want to build my mathematical base before entering graduate school, and for that, I have been planning on taking courses online. However, I am a little confused. I could take these courses at a local college, but it would cost me considerable amounts of money. The material benefit of going to college for these classes is the transcript with grades on it for the adcomms to view and evaluate. However, Coursera offers free courses, but if I spend some money, they would provide a 'verified certificate;' still, with no grades on it to sufficiently allow the adcomms to evaluate my mathematical training.
Therefore, I am not sure where to go from here. It might be helpful to also note that I have very little mathematical training, so these are the courses I am looking to take: statistics and probability, algebra, calculus, real time analysis, and econometrics. Also, I'd appreciate if you could suggest any other good courses.
