Relaxing before the exams

For most students, relaxing before final exams may prove just as difficult as learning Chinese algebra. A good number of students get stomachache and tension headache before exams. They get shaky, sweaty; their hearts starts beating quickly as they wait for the exam papers to be given out.  Most students experience some nerves on the day of the exam; it is normal, but for some it is extreme and more difficult to handle than others.
