Ha that quote.

I'd say in general Hermione isn't the best with stressful situations, remember the devils snare? That's probably why she didn't become an Auror. I do think she's better in the classroom setting but that's nothing to be ashamed of, not everyone is as hands on as Harry and Ron. Also, remember how she panicked during her third year defense against the dark arts exam? She couldn't even get rid of the bogart because it told her that she was going to fail her exams. I don't see this as a bad thing necessarily, it's just part of who she is. Hermione can't be good at everything.
