How do graduate schools look at "non-core" physics courses? If a graduate committee sees the transcript of a student who did well in all the core physics courses (≥B+) but in then see a C or C+ in a non-core physics course, say electronics? Could that essentially break an application or is there not much importance placed on these courses as long as the overall GPA is competitive? Is it worth retaking the class and getting an A? Unfortunately, I severely underestimated the final exam assuming it would be as straightforward as the term tests and decided to focus on my other classes at the time. Went in with a B+ and came out of the course with a C+.
