This is the place to be if you are preparing for nios practical exam. This guide is a no-jargon-friendly guide by Unnati Education. It explains what a student really needs to know: why NIOS practicals are important, how they work, how marks will be awarded, how you can prepare your project and record file, and how the viva works. The guide is written in simple language and focuses on actionable, real-world steps. We support you from start to finish with study materials, complete syllabus coverage, and practical files. Project guidance and viva preparation are also included.
Why NIOS offers practical exams
NIOS is a place for open learning. However, many subjects still require practical skills. The practicals will help you. Practicals assess your ability to apply concepts. You will be asked to run an experiment, use software, handle equipment, organize data, and explain choices. The assessment is not solely based on your final result or output, but also on how well you followed the instructions, recorded observations, and explained them to the examiner in the viva.
Shortly, practicals turn book knowledge into a useful skill. You can gain marks by preparing well.
What NIOS Practicals are scheduled, and when can you expect them?
NIOS Practicals are conducted at your designated examination center. Centers publish a list of groups, so that different groups can attend at different times. For the 2025 session, practicals will be scheduled to:
- Students who are in the first semester of the school year can attend the April-May session.
- Second half of the October-November session
Centers will often run more than one batch in a single day. You can confirm the exact batch, date, and time on your admit card or via the center’s WhatsApp/noticeboard. Check your learner’s portal and messages from the center every few weeks as the exam period approaches.
Practical Subjects
The practical component is commonly found at Secondary (Class 10):
- Science & Technology
- Home Science
- Painting
- Data Entry Operation
The Senior Secondary School (Class 12th) includes a variety of practicals.
- Physics, Chemistry, Biology
- Geography
- Home Science
- Environmental Science
- Mass Communication
- Computer Science
- Painting
- Data Entry Operation
Languages and some humanities courses are usually only theoretical. Unnati Education is able to help you if you are unsure of your subject mix. They can verify which subjects have a practical element and create a plan that suits your exact combination.
Remember the pass and mark criteria.
For each practical subject, a separate mark is given. This is added to the theory marks to determine your final grade. Both components must be passed individually. The typical distributions are as follows:
- In Class 10, weighting can be low (15 marks in Science & Technology, for example) or high (60 in Data Entry Operation, 70 in Paint).
- Computer Science is 60 (theory), plus 40 (practical). Painting can be 30 (theory), plus 70 (practical).
Your score can be significantly boosted by high-weight practicals. A clean file, a steady hand-on job, and a well-organized viva are all factors that will boost your overall percentage.
What is the NIOS practical exam?
The typical practical has 4 moving parts.
- Hands-on tasks: You may perform an activity in the lab, create a painting, or a composition. Or, you might complete a fieldwork report or a data entry task. Method and accuracy are the focus.
- Record/Practical notebook: You submit a neat, complete notebook capturing each practical: aim, apparatus/software and version, underlying principle, stepwise procedure, readings/observations, calculations or prints, graphs where relevant, a short result, and sensible precautions or error sources.
- Project/Portfolio: Some topics add a file or portfolio that shows your initiative, depth, data collection and analysis, neat presentation, and a clear conclusion.
- The examiner may ask short questions about your understanding. For example, he might ask why you need to take a particular step, what you would do if a problem appeared, how you ensure safety, or how you selected your units and scale, as well as where you think an error could occur.
Examiners look for clarity and consistency. You can score well even if the final value of your exam is not perfect if you use the correct method, keep clean records, and answer with understanding.
How to pass the NIOS practical exam -- a simple blueprint for preparation
Then, prepare in layers. Prepare for your NIOS practical exam.
Then, hands-on practice:
First, read the theory and then the practical. The book and bench should be alternated so that you can relate what you read with what you observe.
Multi-runs of each experiment:
Confidence is built through repetition. You should aim to do several clean runs on each task – one for understanding and neatness, one for speed, and one for confidence.
Notebook discipline:
Keep the same format for all entries: clearly numbered headings, labeled tables with units, graphs labeled with axes, and a precise scale, as well as short, precise answers. Date each entry. Margin should be maintained. Use one color of ink for the text and pencils for the diagrams/graphs.
You can feel the project in your heart:
Select a project about which you care. You can either collect primary data or make a neat mini-dataset. Then, you should show the basic analysis. Finally, write a brief, concise conclusion. Prioritize the quality of your work over the fluff.
Viva habit:
You should be able to explain each experiment within 30-60 seconds: the principle behind it, what you did, possible areas of error, and an application in real life. If you can teach it, then you already know it.
Mock day rehearsal:
It is a good idea to simulate an exam. Lay out all your stationery, set a timer, and speak out loud. This helps you to relax and increase your flow.
Sleep, food, calm:
A consistent routine during the week before the exam will earn you more marks than a sprint in a state of panic. Revision should be light, but frequent. Hydrate, rest, and sleep.

What to take with you and how to conduct yourselves
Bring your admit card along with a valid ID and any other subject-specific items, like paint brushes or computer code, if you prefer. Find your station or system early, read the questions calmly, and ask any procedure doubts before starting. Keep the work area neat. Label all items. Write legibly. Do not panic if your plan runs into trouble. Instead, note the problem, follow a methodical approach, and then explain it in the viva.
The center will not allow phones or smart devices unless it is specifically allowed for digital tasks. In case of doubt, it is best to leave the devices outside.
How are marks usually determined in the lab
Examiners search for a consistent pattern:
- Standard steps for a correct and safe method
- Observations look natural, consistent, and well-tabulated
- Calculations with units of measure and significant figures
- The graphs are labeled, labeled and scaled.
- Short and to the point results
- Understanding the process and avoiding mistakes is a good way to understand it.
- The best vivas are confident, direct, and clear.
You do not need to sound like a scientist. Just sounds like you are a student who has worked on this experiment and understands the purpose of each step.
Subject-wise examples of what you can expect
Science & Technology (Class 10): simple physics observations or verifications, basic chemical reactions or observations, brief biology experiments or slides work.
Home Science: demonstrations on food science and textiles; hygiene, household resource management. Charts and file presentations count.
Painting: compositions, still lives, color usage, technique, portfolio. Marks are dependent on both the process as well as finish.
Data entry operations: speed, accuracy, formatting discipline; tables, mail merging, or basic data management. Print output and onscreen neatness also matter.
Physics, Chemistry, Biology (Class 12): standard board-level experiments–verification, titrations, microscopy, slides, measurements with precautions and error reasoning.
Geography: map-reading, field observations, and neat cartographic work.
Environmental Science: Small surveys, charts, and local case studies.
Mass communication: concept note, storyboard or script, recording/editing principles, portfolio.
Computer Science: working program, documented code, and output that has been tested, as well as the ability to explain logic.
Unnati Education has mapped each practical requirement to a realistic method, a notebook model, and, most likely, viva questions.
You can copy a model of a notebook that is clean and high-scoring.
It is easier to write each entry if you follow a strict format.
- The title/target is only a single line.
- Apparatus/Software names with software versions where relevant
- The concept or principle should be written in 2 to 4 lines. Do not write a full page of theory.
- Simple and short procedure with numbered steps
- Observations with units in a table for each reading
- Calculations/Graphs with one neat calculation sample and scaled axes
- One line that answers all the questions.
- You can find the sources of error and warnings in plain language, which is what you actually did.
This format is easy to read and looks professional. It makes it easier for examiners.
The most common mistakes that eat marks silently
Messy tables and missing units. Random significant figures. Overwritten corrections with no clean redraw. Project files that look copied. Rushing and arriving late. Admitting that you “just memorized”. You can replace these with neatness, short check-pauses, calmer explanations, and the willingness to admit “I am not completely sure, but this is my understanding”, when you get stuck.
Things don't always go according to plan.
NIOS has flexibility. If you fail to achieve the required pass mark for a practical, you can either reappear during the next open session or you can use the On-Demand Examination System (ODES) if available at your center and subject. Concentrate your comeback efforts on method discipline and a polished journal, as well as targeted answers in the viva. These are the three levers that will help you score higher.
Details about the 2025 NIOS practical exam -- administrative essentials that you need to track
You can find the schedule and admission cards on your student portal. Practical exam fees are usually modest and paid during registration. Students who qualify may be eligible for discounts. The exact dates and fees may vary depending on the session and subject. So, make sure you keep your notifications enabled and confirm your center, date, and time a few days before the exam. Unnati Education can track this information for you and send out reminders. They can also confirm your slot to avoid any last-minute confusion.
The final advice that you should take into the lab
The practical is always better than the dramatic. Keep your work tidy, label all items, follow directions, show the units, and speak clearly in the viva. Examiners are looking to see that you have understood and put in effort. You’ll get the best marks in practicals if you practice regularly and keep your records clean.
It is now clear what an NIOS exam is, from the purpose and subject matter to the preparation and scoring.
