Millions of students in India appear for various competitive exams to gain admission into undergraduate, postgraduate and professional courses, as well as to secure public sector jobs. Competitive exams are difficult to crack, given the limited number of seats and the large base of aspirants. Every year, a huge number of candidates appear for civil services examinations to secure jobs in the public sector (central government services, the Indian Forests services, combined Medical and Engineering services and Economic service etc). Similarly, exams are conducted each year for gaining admission into different levels of CA, CS and CMA (professional courses). As a result of the rising competition, many students are opting for coaching classes apart from their regular curriculum.
