NIOS Syllabus 2026–27: Class 10 & 12 PDF Download Guide

NIOS Class 10 Syllabus: Subjects and Codes

Secondary is the Class 10 level. Use the codes below as a quick reference when opening the official directory. This is a selection of commonly searched subjects, not the complete list of available options.

Reference: NIOS Secondary course-material directory.

Do not download Senior Secondary Biology or Computer Science as a replacement for a registered Class 10 subject. For example, Science and Technology (212) and Biology (314) belong to different course levels.

If you are already enrolled, make a shortlist from your admission record first. Searching only for a subject name can lead you to the correct topic at the wrong level.

NIOS Class 12 Syllabus: Subjects and Codes

Senior Secondary is the Class 12 level. Familiar subject names can appear at both levels, so the code remains important. Mathematics (211) is not the same course as Mathematics (311).

Reference: NIOS Senior Secondary course-material directory. Check the current prospectus for the full subject list.

For each selected subject, keep its syllabus with the matching books or lesson PDFs. A broad label such as Science, Commerce or Arts is not enough to identify the correct set of files.

How to Download NIOS Syllabus PDFs

1. Start on the official website. Open NIOS and locate Online Course Material, or use the course-page buttons above.
2. Select the right level. Choose Secondary for Class 10 or Senior Secondary for Class 12.
3. Match the code. Find the subject listed in your registration record, not just a similar title.
4. Read the document labels. Look for syllabus, syllabus bifurcation, sample paper, marking scheme and course material. Available files can differ by subject.
5. Check the medium. Where different language versions are provided, choose the one appropriate to your studies.
6. Check applicability. Read any revision or examination-session notice before deciding which lessons to prepare.
7. Save and reopen the PDF. Confirm that the download is complete and the pages are readable.

A simple naming system helps: NIOS-10-English-202-Syllabus.pdf. Save the textbook and TMA booklet with different names. You should be able to tell what a file contains without opening five documents.

If a download does not open

Return to the official directory and try again later, or use another browser. If two official files appear to conflict, note their titles and dates and ask your Study Centre or Regional Centre which applies. Do not assume that a PDF copied into a messaging group is the latest version.

Syllabus, Study Material, TMA and Practicals: What to Save

Once you have the right assignment booklet, our NIOS TMA submission guide explains the upload workflow. Keep the latest official instructions open while preparing and submitting your work.

How to Check Your NIOS Subject Combination

The standard certification route requires passing five subjects, including one or two languages. Up to two additional subjects may be chosen, bringing the total to seven. These are certification rules, not a statement that every examination attempt must contain five papers. See the official NIOS FAQs.

Choice is flexible, but it is not unrestricted. The official Senior Secondary scheme of studies identifies subject groups whose examinations share a date and time. Check those restrictions before finalising a combination.

• Start with your goal: check the subject requirements of any future course you want to enter.
• Check registration: make sure the subjects you plan to study are actually recorded in your admission.
• Check assessment work: allow time for practicals and assignments where applicable.
• Check workload: choose a manageable combination rather than relying on claims that a subject is an “easy pass”.

For an already enrolled learner, downloading a different syllabus does not change the registered subject. Resolve a registration mismatch before building your timetable around it.

NIOS Marks: Do Not Mix TMA With Practical Marks

There is no universal “80 theory + 20 practical” rule for every subject. Theory and practical allocations depend on the subject. TMA is a separate internal-assessment component, not another name for the practical examination.

The 2026–27 prospectus gives internal assessment 20% of the theory weightage for applicable Stream I learners; the public examination carries the remaining 80% of theory weightage. TMA does not apply to registrations under Streams II, III and IV. These are weightages, so do not automatically interpret every question paper as being printed out of 80 marks.

Class 10: the prospectus requires 33% in the public-examination theory-plus-practical total, where applicable, excluding TMA, and 33% in the aggregate including applicable TMA.

Class 12: it requires 33% separately in theory and practical, where applicable, excluding TMA, plus 33% in the aggregate including applicable TMA.

For more explanation, read our NIOS Class 12 passing-marks guide. Always match any worked example to your subject’s actual marks structure.

Is the Syllabus the Same for Public Exams and ODE?

Use the official NIOS subject curriculum as your starting point, but do not assume that the examination date is the only difference between public examinations and the On-Demand Examination route. Check the applicable coverage, question-paper design and stream-specific assessment instructions before preparing.

Public examinations normally follow the April–May and October–November cycles. ODE requires an eligible registration and an available booking; “on demand” does not mean an unrestricted walk-in examination on any day. Check the current schedule and seat availability on SDMIS and read the official ODE overview.

Similarly, do not label a file “April syllabus” or “October syllabus” unless the official document actually limits its applicability that way. Follow the version and notices for your subject and examination route.

Turn the Downloaded Syllabus Into a Study Plan

A folder full of PDFs is only a starting point. Create one short checklist for each subject and use it during the week:

1. List the applicable lessons. Copy their names from your verified syllabus and assessment guidance.
2. Mark your starting point. Use simple labels: not started, learning, practice needed and revised.
3. Plan one achievable task. “Work through two questions” is easier to act on than “finish Mathematics”.
4. Keep assignment work separate. Record the applicable submission task and check its deadline independently.
5. Set aside practical time. Do not leave activity records or practical preparation until theory revision is finished.
6. Review weekly. Give the next available session to a weak topic rather than repeatedly rereading your strongest chapter.

Use the Student Tools Hub for planning helpers. Once your exam subjects are confirmed, the NIOS Exam Fee Calculator can help estimate the applicable public-exam cost; confirm the final amount on the official portal.

Before closing the download page

• Correct course level and subject code?
• Right medium and applicable document version?
• Syllabus and study material saved as separate files?
• Current TMA and practical instructions checked where relevant?
• Sample paper and marking guidance saved if provided?
• Official source link bookmarked for later updates?

If one answer is uncertain, resolve that detail first. It is much easier to replace the wrong file today than to discover the mistake after several weeks of preparation.
