Very Bad Advice
A test-prep company is planning to do formal testing to find out exactly what minor activities (choice of food, clothing worn, etc.) might boost scores a few points on tests like the SAT.

This is all well and good, but the conventional advice on the side contains one very erroneous piece of advice: avoid candy.

Right before I took the bar exam, I was told on good authority that the secret to passing was consuming sufficient chocolate. Though not customarily much of a candy-eater, I procured a bag of chocolate. (I did not steal it. Or, of course, pay for it. Someone had leftover Christmas candy, I think.) I dutifully consumed chocolate at each break. And I passed. Now, how can you argue with that?
