Detailed Exam Pattern

The Bihar APO selection process consists of three key stages: the Preliminary Exam, the Mains Exam, and the Interview.

1. Preliminary Examination (Screening Test) This stage serves as a screening process. The marks obtained here are not counted toward the final merit list. It consists of two objective-type papers (Multiple Choice Questions) available in both Hindi and English.

2. Mains Examination (Written Test) Candidates who clear the Prelims move to the Mains, which is descriptive (subjective) in nature. These marks are crucial as they count toward the final selection.

• Paper I (General Studies): 100 Marks, 3 Hours.
• Paper II (Hindi Language): 100 Marks, 3 Hours. This is a qualifying paper where you must score at least 30 marks.
• Paper III (English Language): 100 Marks, 3 Hours. This is also a qualifying paper with a minimum requirement of 30 marks.
• Paper IV (Bharatiya Nyaya Sanhita, 2023): 150 Marks, 3 Hours.
• Paper V (Bharatiya Sakshya Adhiniyam, 2023): 150 Marks, 3 Hours.
• Paper VI (BNSS, 2023 and CPC, 1908): 150 Marks, 3 Hours. This is split into 75 marks for Bharatiya Nagarik Suraksha Sanhita and 75 marks for the Civil Procedure Code.
• Paper VII (Constitutional Law of India): 150 Marks, 3 Hours.
• Paper VIII (Other Special Laws): 150 Marks, 3 Hours.
