Wow, you can have it as a catalyst for Abby.
On a serious side note though, try to divert your attention on other things first before that exam. As I always say to myself even on the board examinations: I'll cross the bridge when I get there.
Also, think of a silent prayer before examinations. Might not be inspiring, but at least it can enable your senses to be focused on those 5 - 10 minutes of silence.
