re: When it comes to people asking what your degree is in.

I mean, you can say whatever you want. When someone asks what degree you have, they almost always mean what did you major in. A concentration is not the same as a major. So if you say you have a biology degree, you'll clearly be misleading them, so don't be surprised if they mock you for it. But if you feel that strongly about it, there's no law that says you can't claim to have biology degree.
