You have to love the duality of Amelia's intelligence:
On the one hand, as we're reminded of in this chapter, she's the top ranked student in the Special Course for the best of the brightest. It's also been previously stated that she had the best test scores of her year before becoming the only first year to enter the Special Course.
On the other hand, "I used to wander alone in the sticks all the time, I'll be fine. Never mind that I was explicitly warned about potential foreign agents making a move during the event. What? You think I should be careful because I could be valuable either as Sarge's assistant or a hostage? I'll be fine".
