Exam Stress Preparation of exams is indeed a stressful period. Lack of concentration is because your mind worries about the Result of the exam most of the time,even while reading. This is what we call as ' Living in the Future'. Obviously when one's mind is not in the present, the reading wont get registered which ultimately leads to poor performance and lack of confidence. Break this vicious cycle. Dont worry about what is going to happen and do your duty with focused concentration. All the best
