I was just wondering how it would look if you got an A in a graduate level course when you got a B(mostly) or worse in the undergraduate version(s) of the course. On one hand, the schools probably won't worry about you actually knowing the material which is critical, if you have a less than ideal GPA/academic history like me, but everyone knows the curve is higher in graduate courses, even though it is also part of an overall turn-around trend. So far it is only for one course, but I'm considering staying on an extra year for a second degree in math and more research, which gives me plenty of time to do more if I choose to.
Possible factors in this is that I'm not applying to the "top" schools for the most part like most people on this forum(so I don't need to worry *as* much about looking good relative to everyone else, more important that I can handle the material and the overall trajectory of grades is good, to my understanding), and possible letter of recommendation from one of the teachers that I have in the courses, possibly two if I do more of them.
Thank you for your time. I sincerely appreciate it. As an added question, will people care if you take the extra year to do that-it's really just an extra semester, the spring afterwards I'm free not to do anything, if I choose.
