Take deep breaths, try to think about your capabilities, believe that you can do it, you are prepared & you have it under control, repeat the can spirit with yourself constantly & the way you're there to ignite your talents & use your ability to win your goals. & that's the reason you came that far, you stood until the exam date & you're in the class for one reason, to win, you had lights of success in your heart, otherwise you wouldn't be there, so that means you've been ready for such battle, & now this is another step to take toward your future, the future that you want to reach, you knew it would come to there, so all you have to do is remain calm, gain focus, believe in yourself & makes it happen. Your time is now. It's your turn to cross the bridge. The bridge that connects you to the elevator that suppose to locates you on the top.
