How to Calculate Your Score

Here’s how you can calculate your expected marks using the BPSC AE 2025 Answer Key:

• Award 1 mark for every correct answer (check official marking scheme for exact values).

• Subtract marks only if there is negative marking (some BPSC AE exams may not have it).

• Unanswered questions carry 0 marks.

• Total the marks for all correct responses and subtract any penalties for incorrect ones.

This will give you an estimated score, which you can use to assess your chances of clearing the cut-off.

How to Raise Objections (If Any)

If a candidate believes that a particular answer provided in the official answer key is incorrect, BPSC provides the option to raise objections. This ensures fairness and allows transparency in the recruitment process.

Steps to File Objection:

1. Visit the official website of BPSC.

2. Look for the objection submission link next to the answer key notification.

3. Click and login using your exam credentials (Registration ID, Roll Number, or DOB).

4. Select the question(s) you want to object to.

5. Provide a valid explanation with reference documents or proof (from standard textbooks or government-authenticated sources).

6. Submit the objection before the last date mentioned in the notification.

Only valid objections backed by credible sources will be considered during the review process.

Final Answer Key and Result Process

After the objection window closes, BPSC reviews all challenges submitted by candidates. Based on the findings, a final revised answer key is published. This key is considered binding and final, and results are prepared based on it.

Once the evaluation is complete, BPSC publishes the result, which includes:

• List of qualified candidates

• Cut-off marks

• Instructions for further stages (Document Verification or Interview, if applicable)

Candidates are advised to regularly check the BPSC website for updates and ensure their email and phone number registered with BPSC are active for receiving alerts.

While the final cut-off will be announced with the result, here’s a tentative estimate based on previous trends:

• EWS: 70–80 marks

• OBC: 68–78 marks

• SC/ST: 60–70 marks
