This page collects every NIOS Class 12 Question Paper 2025 released for the April and October public examinations, arranged by subject code so you can open the exact PDF you need in one click. Each row carries the paper itself plus a solution request link, and the vocational papers from the April session are listed in a separate grid below.

The April 2025 papers were printed in Set A, Set B and Set C variants for most academic subjects, which is useful because the three sets rotate the same syllabus areas through different question numbers. Attempt one set fully, then scan the other two for phrasing you have not seen.

Total academic subjects listed: 50. Language, science, commerce, humanities and skill based codes are all included in the grid above.

Vocational Subject Papers from the April 2025 Session

Vocational candidates sit a separate paper alongside their academic subjects. These seven codes were released for the April session and follow a shorter, application heavy structure compared with the academic papers.

Most October 2025 academic PDFs are hosted directly. Where the PDF is not yet uploaded, the Download Paper button opens a WhatsApp request so a counsellor can send the scanned copy for that subject code. Solutions for every code follow the same request route.

Total academic subjects listed: 50. Rows marked Request PDF are papers still being digitised after the October session.

Exam Pattern and Marking Scheme for Senior Secondary Papers

Most non practical theory subjects at senior secondary level carry 80 marks in the public examination and 20 marks through the Tutor Marked Assignment. Practical subjects split the weighting differently, with a share reserved for the practical file and viva. [VERIFY marks split for practical codes against the current scheme on nios.ac.in before relying on it.]

• Duration: three hours for a full theory paper.
• Question types: objective and very short answer items, short answer items, and long answer items that carry the largest single blocks of marks.
• Sets: Set A, Set B and Set C for many academic codes in the same session.
• TMA: submitted to the study centre and counted towards the final result.

Reading the paper before reading the textbook changes how you revise. Once you have seen how a chapter is actually examined, you stop memorising sections that never appear and start writing answers in the shape the marking scheme rewards.

How to Practise These Papers for a Higher Score

1. Sit the paper cold. Open the PDF, set a three hour timer, and write on loose sheets exactly as you would in the examination hall.
2. Mark the long answers first. The heaviest items decide your band, so check those against the syllabus before you look at anything else.
3. Repeat the same code across sessions. Solve April 2025 and October 2025 for the same subject and note which topics survived both papers.
4. Keep an error sheet. One page per subject listing every question you could not attempt, revisited weekly.
5. Time the writing, not just the thinking. Most students lose marks on the last two questions because the clock ran out, not because the topic was unknown.

If you want the written solution set for a specific subject and session, message the NIOS desk with the subject code and the session name.

Recurring Question Areas by Subject Group

The areas below appear consistently across the papers listed on this page. They are a starting point for revision, not a substitute for the full syllabus, and they should be checked against the paper you download.

Science group

• Physics (312): current electricity, magnetic effects, optics and modern physics numericals.
• Chemistry (313): chemical bonding, equilibrium, organic conversions and named reactions.
• Biology (314): reproduction, human physiology, genetics and ecology based long answers.
• Mathematics (311): calculus, matrices, probability and vector questions with stepwise working.

Commerce group

Where These Papers Sit in Your Preparation

A downloaded paper is only a diagnostic tool until you write it. Students who attempt three sessions of the same code in timed conditions usually spot their own weak chapters faster than any coaching note can tell them. Pair the paper with the matching TMA and the practical file, if your subject has one, and your revision is effectively complete.
