everyone at least once in a life passed some kind of exam. should we worry about the results of the exam after we did that? at first glance, an answer to this question seems to be a piece of cake. but people actually split down in the middle with no clear confidence. being in the dark about our mark makes us feeling nervous. some people even become down in the dumps, i mean, they fall into depression bothering themselves. they even may understand that it doesn’t make any sense but they commonly can’t help it. but there is a category of people that can manage to not let their hairs down. they stay still whatever they do, particularly, sit in for a test.
