How to Calculate Marks Using the RRB MI Answer Key

Once you have downloaded the answer key, you can calculate your probable score using the marking scheme provided by the RRB. The CBT consists of 100 questions, each carrying 1 mark. Here is the marking scheme:

• Correct Answer: +1 mark
• Incorrect Answer: -1/3 (0.33) mark deducted
• Unattempted Question: 0 marks

Formula: Total Marks = (Number of Correct Answers × 1) - (Number of Wrong Answers × 0.33)

For example, if you answered 80 questions correctly and 10 incorrectly, your estimated score would be (80 × 1) - (10 × 0.33) = 80 - 3.3 = 76.7 marks. This score is an estimate and may change after the final answer key is released.
