How to Fill an OMR Sheet for the Bihar APO Prelims Exam 2026?

Candidates should follow the simple instructions given to fill out the OMR sheet for the Bihar APO Prelims examination 2026. 

Step 1: Basic Details

Fill out the basic information in the OMR sheet carefully. It includes the following details

  • Name

  • Roll Number

  • Question booklet details

Check the information once done to avoid any mistakes. 

Step 2: Pen Selection and No Correction Rule

Candidates need to use only the black ballpoint pen to mark the bubbles in the OMR sheet. Any mistake occurs in the exam while marking the OMR sheet. Candidates are not allowed to use any whitener to correct the mistakes. 

Step 3: Paper Attempting and OMR Filling Strategy

Candidates need to follow the simple strategy for marking the questions in the exam.

  1. Round 1: Sure Shot Questions

  • Read the entire paper first. Mark answers the question paper.

  • Identify questions you are 100% confident about, with no doubt.

  • Fill the OMR for these Sure Shot questions in the first reading itself. This boosts confidence.

  1. Round 2: 50-50 Questions

  • After the first round, address questions where you were unsure between one or two options. Analyse and solve them carefully.

  1. Round 3: Doubtful and Unknown Questions

  • In the final round, tackle questions you found completely unknown or those requiring educated guesses based on elimination.

The Slot Method for OMR Transfer

Working in slots of 5 to 10 questions is crucial to prevent the "Domino Effect." (Memory Tip: Prevent the "Domino Effect" – bubble in slots.)

  • Do not fill the entire OMR sheet at once.

  • Why? This limits the impact of a bubbling error to a small group of questions.

  • Procedure: Answer 5-10 questions on your question paper, then transfer those answers to the OMR sheet, double-checking each transfer. Repeat this process for the next slot.

Step 4: Negative Marking and Smart Guessing

  1. Negative Marking Instruction:

  • Always read the instructions on the question paper regarding negative marking.

  • Confirm with the invigilator if negative marking applies before attempting. Ensure this point is clarified.

  1. Smart Guessing Strategy (if no Negative Marking):

  • Do not guess blindly. After attempting your sure-shot questions, use the elimination method for others.

  • Actively reject options that are clearly incorrect or inapplicable.

  • This reasoned approach can significantly improve the accuracy of your guesses.

  • Recommendation: If there is no negative marking, attempt all questions, but always apply your mind and reason to your guesses.

  • Move inwards in a spiral motion.

  • Do not leave any white dots in the middle.

  • Do not mark with a tick or a cross.

  • Any incomplete or improperly marked bubble will not be read by the computer.
