I plan to apply to graduate programs in a field unrelated to my current undergraduate studies. Other questions indicate that this is relatively common, but my question is: is there any value in obtaining a degree in my desired field over only taking relevant courses?
I think that having a relevant degree could only be beneficial, but talking with advisors and professors gives me the impression that there is no need to have a relevant degree. Surprisingly to me, there is even some agreement that this could be harmful, since I would require an extra semester to graduate. I'm in no hurry to graduate (currently planning for four years) so I don't quite understand their concerns. Am I missing something entirely?
Do I even need to consider getting the extra degree or is it really unnecessary?
