APSC Answer Key Objection 2026 – Online Login Process
Objections are accepted only through the online portal. Postal, email or hand-delivered representations are not entertained.
Details Required at Login
The objection login page asks for the following:
- Advertisement Number – select 22/2025
- Post Name – select from Forest Ranger (Botany), Forest Ranger (Zoology), Forest Ranger (Civil Engineering), Forest Ranger (Mechanical Engineering), Forest Ranger (Chemical Engineering)
- Roll Number
- Date of Birth in dd-mm-yyyy format
- Registered Mobile Number
- Captcha text
Step-by-Step Objection Procedure
- Go to apsc.nic.in and open the Answer Key Objection link.
- Choose Advertisement No. 22/2025 from the dropdown.
- Select your post name and optional subject.
- Enter your roll number, date of birth and registered mobile number.
- Fill in the captcha text and log in.
- Select your question booklet series and the question number you wish to challenge.
- State the answer you believe is correct and write a brief justification.
- Upload authentic documentary proof in support of your claim.
- Submit and download the acknowledgement for your records.
Tips for Filing a Strong Objection
- Cite standard textbooks, IS codes, government publications or peer-reviewed sources. For engineering papers, references such as IS codes, standard design textbooks or established handbooks carry far more weight than coaching notes.
- Mention the exact page number, edition and author of the source you are quoting.
- Raise objections only where you are confident, with evidence — vague or unsupported claims are routinely rejected.
- File one objection per question rather than clubbing several questions together.
- Complete the process well before the deadline; the server usually slows down on the last day.
- Remember that the series matters — question numbers differ across Series A, B, C and D.
How to Calculate Your Expected Score
Match every response on your rough copy against the key for your booklet series, then apply the marking scheme printed in the official advertisement. Count the questions answered correctly, apply any negative marking specified for wrong answers, and treat unattempted questions as zero. Since the key is provisional, treat the figure as an estimate — a dropped or revised question can shift the total either way.
What Happens After the Objection Window Closes
APSC examines every claim received, consults subject experts where required, and then publishes a final answer key. Answers may be corrected, and questions found to be ambiguous or incorrect may be dropped, with marks adjusted for all candidates accordingly. Results are prepared on the basis of the final key only. The Commission’s decision on objections is final, and no individual replies are sent to candidates.
Candidates who clear the written stage move on to the subsequent stages of selection as laid down in Advertisement No. 22/2025, which for the Forest Ranger post includes physical standard and endurance requirements along with a personality test.
