Step 3: Count Incorrect Answers

Step 4: Apply the Score Formula

• Multiply the total number of correct answers by 2
• Multiply the total number of incorrect answers by 0.50

Total Marks = (Correct Answers × 2) − (Incorrect Answers × 0.50)

Step 5: Find Your Approximate SSC CHSL Tier 1 Score

The result obtained from the above formula will be your estimated raw score in SSC CHSL Tier 1, before normalization and final result processing by SSC.

Why Your Estimated Marks May Differ from the Final Result

Even after careful calculation, your estimated marks may not match exactly with the final score shown in the result. Here are the major reasons:

1. Objection Handling

If you raise objections against any question or answer and SSC accepts those objections, the official key may change. This can lead to an increase (or sometimes adjustment) in your final score.

2. Dropped or Modified Questions

Sometimes SSC may find some questions to be ambiguous, incorrect or out of syllabus. In such cases, those questions may be dropped, and full marks can be awarded to all candidates for those questions, irrespective of their response.

3. Normalisation in SSC CHSL Exam

SSC CHSL Tier 1 is conducted in multiple shifts with slightly varying difficulty levels. To ensure fairness, SSC uses a normalization formula to balance scores across different shifts. Due to this, your final normalized marks may be a little higher or lower than the raw marks you calculated from the answer key.

Tips for Candidates After Checking SSC CHSL Answer Key 2025

• Use the answer key only to get a fair idea of your performance and expected score.
• Do not treat tentative marks as the final result, as normalization and objections can change scores.
• Raise objections with proper proof and within the given deadline if you find any discrepancy.
• Compare your estimated score with previous years’ SSC CHSL cut offs to understand your selection chances.
• If your expected score is close to or above past cut offs, start preparing seriously for SSC CHSL Tier 2.

Coaching institutes and online platforms like Aspire Study provide SSC exam content, including SSC exam updates, sample papers, mock tests, guidance sessions and more. You can also join dedicated SSC online batches to prepare systematically for upcoming stages of the examination.
