I am an undergrad majoring in Math and want to apply for a PhD in Economics (maybe in theory and Econometrics). I have taken the intro series (intro micro and macro) already. Since I am about to graduate, I do not have many quotas for courses selection. If I can choose between taking the intermediate series (intermed micro, macro and metrics) or the advanced series (advanced micro, macro and metrics, intended for graduate students), which one is better?
In other words, if I have taken the advanced series, will that I haven't taken the intermed series become a disadvantage when it comes to PhD application? Or are both the intermed and advanced series essential and I should take both by giving up on some math courses?
