Question

Before the examination it is true that to eat an hard boiled egg is advantage? what is possible effect?

Answer 1

I assume you mean a test, like a math exam...  Any good high protein meal, high complex carb meal, not just an egg, is preferable to a high simple carb meal, such as a PopTart.

Answer 2

Eggs are easy source of protein for breakfast. I heard that the brain can only burn glucose. I don't see why hard boiled eggs have any advantage for exams.
