Examinations play a very vital role for assessing our skills that we learn throughout the year.
It is important, as without having a particular deadline, human brain usually does not take things seriously.
Having deadlines, target and a healthy competition among our peer group helps us think out of the box and work harder to outshine and get recognition.
It does become dreadful at times, but the efforts put in with other assignments and homeworks makes one self-sufficient and also builds the cognitive skills.
It also helps in building the power to do multi-tasking. We belong to era where handling multiple things at the same time with the same efficiency is important.
