I guess the more you stress shows the more you care about school. I am not a person that gets stressed or nervous over school, mainly because i really don't care what score i get just as long as i do my best. I believe that school is not the ticket to your dreams, just look at the number of extremely successful people like Bill Gates and Dave Grohl that didn't even finish school. I measure success qualitatively not quantitatively. Always remember that there are many ways to get where you want to go, some just take more time, but in ways that's a good thing, to me it's all about the journey, not the destination, well that's my rant for today, i wish you guys all the best for your exams
