Hi friends,
I think it would be a great appreciation to students before going to appear in exams. As the students who are scared even to enter the exam hall can prepare themselve by testing a bit of pressure and can get aware of manner of marking they are going to apply. Moreover we can get idea that how we are supposed to present in exams.
Conclusively, in my perspective, it is appreciable and should be applied mendatorily as a tool of eligibility.
