Cracking the civil service examinations of UPSC is not a piece of cake. The UPSC is believed to be one of the toughest exams in India. The exam is divided into three steps. The first is the UPSC prelims, which are followed by the mains. Lastly comes the personality exam. This is an interview. Each of these exams is a clearance test that determines the examinee’s rank in the final list. The Prelims All the questions in this exam are made of objective types based on multiple options, from which one is the correct answer. Each correct answer is allotted one mark, and one-third mark is deducted for each wrong call. To clear this exam, the student must score an aggregate of thirty-three percent. Unlike the other two exams, this is just a clearance test and holds no weightage in the final list.
