Which Answer Key Should You Download?
Every candidate needs to check the General Studies Paper I answer key.
You must also download the Paper II answer key for the optional subject you selected in your application. BPSC has released separate provisional keys for:
- General Studies
- Physics
- Chemistry
- Life Science
- Environmental Science
Do not compare your answers with every optional paper. Use only General Studies and the optional subject that appeared on your question booklet.
How to Download BPSC Assistant Environmental Scientist Answer Key 2026
Follow these steps to find the answer key on the official BPSC website:
- Open the Bihar Public Service Commission website.
- Go to the Advertisement or latest notices section.
- Look for Advertisement No. 88/2025.
- Open the notice for the Assistant Environmental Scientist provisional answer key.
- Select General Studies or your relevant optional subject.
- Download the PDF to your phone or computer.
- Keep a saved copy until the final result is announced.
The official website provides separate PDFs for all five subjects. Candidates should use the official key instead of relying only on coaching-centre or social-media solutions.
Check Your Question Booklet Series Carefully
The answer-key PDFs show different question numbers for each booklet series. A single row may contain question numbers from Series A, B, C, and D, followed by the correct answer.
For example, the General Studies key maps questions across all four series. This means you should first confirm your booklet series and then follow the matching question-number column. Comparing answers with the wrong series may give you an incorrect score estimate.
The optional-subject PDFs also use series-based question mapping. The Environmental Science key, for example, displays separate question numbers for the different booklet series before listing the answer.
One General Studies Question Was Deleted
A useful detail in the provisional General Studies key is that the first mapped row has been marked Deleted.
It applies to:
- Series A: Question 1
- Series B: Question 31
- Series C: Question 61
- Series D: Question 81
Candidates should not treat this row as a normal correct or incorrect answer while estimating their probable score. The final treatment of the deleted question will depend on BPSC’s final decision and examination rules.
How to Estimate Your Probable Score
Start by matching your recorded responses with the correct answer-key series.
Count your correct, incorrect, unanswered, and deleted questions separately. After that, apply the official marking rules mentioned in Advertisement No. 88/2025.
Use this simple worksheet:
| Response Type | Number of Questions |
|---|---|
| Correct answers | ___ |
| Incorrect answers | ___ |
| Unanswered questions | ___ |
| Deleted questions | ___ |
Your calculated score will only be an estimate. The provisional answer key can change after BPSC reviews the objections. Use the final answer key for a more reliable score calculation.
BPSC AES Answer Key Objection Window
BPSC allowed candidates to challenge answers they believed were incorrect. The online objection window was available from July 8 to July 12, 2026.
Candidates were required to log in to their dashboard, select the disputed question and provide valid supporting material. The reported objection fee was ₹250 for each challenged question. Objections sent after the deadline or through another method were not to be accepted.
The objection window is now closed. Candidates should not make payments through unofficial links or send documents to unknown email addresses.
What Happens After the Provisional Answer Key?
BPSC will review the objections received from candidates. Subject experts may examine the disputed questions and supporting references.
After this process, the Commission may:
- Keep an answer unchanged
- Revise an answer
- Accept more than one option
- Delete a disputed question
BPSC is expected to prepare the examination result using the final accepted answers. At the time of this update, no confirmed date for the final answer key or result has been announced in the notices reviewed.
