When I was a kid I read that mint flavorings can help the blood vessels in your head dilate, increasing the amount of blood flow to your brain and therefore helping you do better on studying and tests.

Whenever I have a test to study for or to take, I made it a point to keep some sort of mint flavored candy around, and consistently across the board I have always done better on tests than my peers.

That being said, it is entirely plausible that this is a placebo effect, but I like my placebo and it works for me. Perhaps it will work for you as well.

It was incredibly common at my school for teachers to hand out lifesaver mints before standardized tests.

I always start chewing gum before a licensing exam. Minty gum and not fruit gum. It also helps me concentrate and eat less. When I was skinny skinny I chewed gum like a candy kid and worked retail.
