How to Calculate Marks Using OSSC CTSRE Answer Key 2026?

Understanding the marking scheme is essential for estimating your preliminary exam score accurately. The OSSC CTSRE-2025 Preliminary Examination follows a standard objective pattern with negative marking.

Marking Scheme & Formula

• Correct Answer: +1 Mark
• Incorrect Answer: -0.25 Marks (Negative marking of one-fourth of the marks assigned to an incorrectly answered question)
• Unattempted Question: 0 Marks
• Total Marks for Preliminary Exam: 150

The formula to calculate your estimated score is:

Estimated Marks = (Correct Answers × 1) − (Incorrect Answers × 0.25)

Example: If you answered 100 questions correctly and 20 incorrectly, your score would be: 100 × 1 − 20 × 0.25 = 95 Marks.

Note: Always confirm the exact marking scheme from the official examination instructions. The score calculated using the provisional answer key is an estimate and may change if the commission revises answers after objection review.
