Does a B in a class look worse for graduate school admissions than an audit, given I'm not expected to have the class in the first place?
More specifically, I'm studying abroad and taking five math classes. When I go back to my home institution, by the time I graduate I'll have exhausted all the math courses there, so the maximum math courses I'm "expected" to have is those plus four (four classes being a typical semester).
I have the opportunity to change a class to audit, even after I know my grades, so my question is, if there is a class I might get a B in (functional analysis, if you care), do you think having a B would look less impressive than not taking the course (or does audit risk the same sort of judgement)?
Does my question make sense? Does a B look "weak" when applying to grad school (even in comparison to nothing)?
