Board exams are very close so many students might be going through lots of pshychological turmoils or may be under stress. My concern is their mental health which should not be compromised. My advise to all dear students is to remain calm, relax , happy and excited as after a long period you are the first who will be appearing for their offline exam. Appearing exam at your centre , in your class with your classmates is a superb experience, just don't get panic! all of you will rock ✌
