I remember my friend told me her trick during the SAT was to tell them she was hypoglycemic, because otherwise they wouldn’t let her bring in a small snack to eat. Her logic was that during the SAT, the body consumes so much energy that replenishing sugar is necessary half way through for proper brain function, and they won’t let you bring in food unless you have some sort of issue. But the SAT creates the issue!

I have no idea if she was right, but she did do better than me on the SAT, and she is a doctor now, so suffice it to say I always have a snack when coding. You know, for thinking.
