Trying to date a TA

[Betarulz!]

So I asked my genetics TA that I have a crush on to a date party and she turned me down b/c she didn't feel comfortable about me being a student in her recitation section.

I need to come up with some sort of way around this, so that if she rejects me, I'll know it's b/c of me, not the sequence of classes I've taken.

She is an undergrad, and she's in my Biochemistry class, so I see her there twice a week adn then of course during my recitation.

Any thoughts, or ways to convince her that there isn't a conflict of interests or favortism? Any ways around this other than dropping the class (which was my first thought but isn't possible)?
