Civil Services Examination demands critical thinking, conceptual clarity, an ability to express powerfully and the wherewithal to apply the learnt knowledge to a range of situations and scenarios - not just textbook, rote memory learning. This applies to both mandatory papers like General Studies, as well as optional disciplines.
In addition to hard work, civil services examination requires a mentor who can guide, coach and help a student navigate through the myriad areas of study, labyrinth of study material and plethora of online resources. One of the reasons why many brilliant youngsters do not even reckon the Civil Services as a career option is this daunting task of manoeuvring through the chaos of preparation.
There are others like working professionals, home makers, people in family businesses, who may have all the abilities to get through the examination and a passion to serve the Nation, but do not pursue it because they cannot travel out for coaching for an year or two, do not have six to eight hours a day to sit through the classes and experience a dearth of quality online resources prepared by professionals. Ease of use and mobility are other factors that dissuade many from embracing emerging technologies that deploy e-learning.
There are still other groups of aspirants who may have had an opportunity to give an attempt or two in the past, but must have dropped the idea for various reasons. They need an access to online resources that can help them revisit and revise the subjects once the courses are completed long back.
