The competitive exams of the today are virtually a race against time. The candidate is expected to perform an incredible amount of mathematical world in a very short time. The time available for sorting out one question ranges from 0.25 to 0.75 minutes. Given such a scenario, traditional methods of solving questions seem anachronistic outdated, to put it simply.
