No negative marking in BPSC ASO changes how you should approach every mock test session.

• Attempt all 150 Prelims questions without leaving any blank — wrong answers cost zero marks
• Maintain a pace of 54 seconds per question — 2 hours 15 minutes divided by 150 questions
• Target 90 or above in mock tests to stay safe above the 45-mark qualifying cut-off
• Use Bihar history, culture, and economy questions as scoring anchors — they appear in every Bihar ASO exam cycle
• For Mains open-book practice, mark your NCERT and BSEB textbooks with topic-to-page sticky notes before the actual test

• Review wrong answers immediately after each Bihar PSC ASO mock test session for faster retention
