• Not all NIOS subjects have practicals – Only specific subjects require lab/practical work
• Practical marks add directly to theory marks – They boost your final percentage significantly
• You can FAIL the subject if you fail the practical (especially Class 12 – must pass both separately)
• Practical exams held 1-2 months BEFORE theory exams – Usually January for April session, August for October session
• You choose which 10 experiments to include – Flexibility to select easier experiments
• Handwritten files are universally accepted – Printed files are accepted at some centres (confirm first)
• External examiner evaluates – Not your regular teacher
• Viva voce is part of practical – Oral questions worth 8-12 marks

NIOS Practical Subjects Overview

Are you a NIOS student confused about which subjects have practicals? Worried about practical exam marks and how they affect your final result? You’re not alone. Every year, thousands of NIOS students search for clarity on useful subjects, marking schemes, and exam patterns.

Not all NIOS subjects have practical exams. According to the official NIOS examination scheme, practical exams are mandatory only for specific subjects in both Secondary (Class 10) and Senior Secondary (Class 12) levels.

Key Points About NIOS Practicals:

• Practical marks directly add to your total score (not separate from theory)
• You cannot pass a subject if you fail the practical component (especially Class 12)
• Practical exams are held at designated NIOS exam centres
• An external examiner evaluates your practical file and performance
• Practical file submission is compulsory even if you don’t attend the practical exam
• You choose which experiments to include (typically 10 from a larger list)

⚠️ Important: NIOS TMA vs Practical – Know the Difference {#tma-vs-practical}

Many NIOS students confuse the TMA (Tutor-Marked Assignment) with the Practical Exam. They are completely different components with different requirements and marking schemes.

What is NIOS TMA?

TMA = Tutor Marked Assignment

• 📝 Type: Written assignment (questions and answers)
• 🏠 Where: Complete at home
• 📤 Submission: Upload online on the NIOS portal
• 📅 Deadline: Before theory exam (usually 3-4 months before)
• 💯 Marks: 20 marks (added to final result)
• 👨‍🏫 Evaluation: Your study centre teacher checks
• ⏱️ Time: No time limit, work at your pace

What is NIOS Practical?

Practical = Laboratory Examination

• Type: Physical experiments/lab work
• Where: At the designated NIOS exam centre
• Submission: Practical file + experiment on the spot
• Date: Fixed exam date (1-2 months before theory)
• Marks: 15-70 marks (depending on subject)
• Evaluation: The external examiner evaluates
• Time: Fixed duration (2-3 hours at the centre)

Side-by-Side Comparison

Which Subjects Have Both TMA + Practical?

Class 12 Science Stream:

Physics (312): TMA (20) + Practical (20) + Theory (80) = 120 total → scaled to 100

Chemistry (313): TMA (20) + Practical (20) + Theory (80) = 120 total → scaled to 100

Biology (314): TMA (20) + Practical (20) + Theory (80) = 120 total → scaled to 100

Class 10:

Science (212): TMA (20) + Practical (15) + Theory (85) = 120 total → scaled to 100

Mathematics (211): TMA (20) + Practical (15) + Theory (85) = 120 total → scaled to 100

Common Mistakes Students Make:

Mistake 1: “I submitted TMA, so I don’t need the practical file”
Reality: Both are separate and compulsory

Mistake 2: “TMA and practical file are the same thing”
Reality: TMA is a Q&A assignment, and the practical is an experiment file

Mistake 3: “I can submit a practical file online like TMA”
Reality: Practical file submitted physically at the exam centre
Mistake 4: “TMA marks replace practical marks”
Reality: Both marks add separately to your total

How NIOS Practical Marks Affect Your Result {#impact-on-result}

Critical Facts You Must Know:

1. Passing Criteria (Class 10 vs Class 12) – READ CAREFULLY ⚠️
For Class 12 (Senior Secondary):

• You MUST score a minimum 33% in Theory separately
• You MUST score a minimum 33% in Practical separately
• If you fail the practical (below 33%), you FAIL the entire subject
• Even if theory is 80/80, practical 5/20 = SUBJECT FAIL

For Class 10 (Secondary):

• You need 33% marks in AGGREGATE (Theory + Practical + TMA combined)
•  Technically, you can pass with low practical if theory compensates
•  BUT: Skipping or failing the practical makes overall passing much harder
• Low practical ruins your percentage even if you pass

Example Calculations:
Class 12 Physics (312) – Must Pass Both Separately :

• Theory: 65/80 (81% – Pass ✅)
• Practical: 5/20 (25% – Fail ❌ below 33%)
• Result: SUBJECT FAIL ❌ (must reappear for both theory and practical)

Class 10 Science (212) – Aggregate System:

• Theory: 70/85 (82%)
• Practical: 4/15 (27% – below 33%)
• TMA: 18/20 (90%)
• Total: 92/120 = 76.67% (Pass ✅ – aggregate above 33%)
• BUT: Overall percentage reduced from potential 90%+ to 76%

________________________________________

⚠️ Don’t Risk Your Result: Even Class 10 students should aim for good practical marks to boost their percentage!
🎯 Get High-Scoring Practical File Now – Don’t Leave Marks On Table →

________________________________________

2. Practical marks are added directly to theory marks

Your final subject marks = Theory marks + Practical marks

Example for Physics (Class 12):

• Theory scored: 65/80
• Practical scored: 18/20
• Final marks: 83/100 ✅
• Percentage: 83% (excellent!)

Same student with poor practical:

• Theory scored: 65/80 (same)
• Practical scored: 8/20 (poor file, nervous viva)
• Final marks: 73/100
• Percentage: 73% (10% drop!)

Impact on Career:

• 83% = Eligible for top colleges
• 73% = Many colleges are out of reach

3. The practical exam is compulsory attendance
If you don’t appear for the practical exam, you get ABSENT in the subject, regardless of theory performance.

• The theory exam won’t be evaluated
• All preparation wasted
• Must reappear next session for both theory and practical

4. Practical file submission is mandatory

• Even if you don’t attend the practical exam (medical emergency, etc.), you must submit the practical file at the exam centre.
• Some centres give grace marks for file submission
• Shows intent to complete course requirements
• May help in exceptional consideration cases

________________________________________

Common Mistakes Students Make in NIOS Practicals

Mistake #1: Starting Practical File Too Late ⏰
Problem: Students start writing the practical file 2-3 days before the submission deadline

Why this fails:

• Rush leads to messy handwriting
• Diagrams are of poor quality
• Mistakes and overwriting
• No time for the teacher’s signature
• Mental stress and panic

Solution: Start at least 20-25 days before the exam. Write 1-2 experiments daily. This gives:

• Clean, neat presentation
• Time to draw good diagrams
• Opportunity to get teacher feedback
• Peace of mind

________________________________________

Mistake #2: Copying Observations from Friends 📋
Problem: All students in a group have identical observations (same readings to the decimal point)

Why this fails:

• Examiner easily catches this
• Reduces the credibility of the entire file
• May mark all files as copied
• Affects the viva questioning

Solution: Use realistic but slightly different values

• Example: Friend’s reading: 2.54 cm
• Your reading: 2.52 cm or 2.56 cm (slight variation)
• This shows you actually performed experiments

________________________________________

Mistake #3: Not Practising Experiments Hands-On 🧪
Problem: Students only read procedures, never actually do experiments

Why this fails:

• Nervous during the exam
• Don’t know how to use the apparatus
• Take wrong readings
• Fumble during performance
• The examiner can tell you haven’t practised

Solution: Practice at least five main experiments hands-on at the study centre or school lab

• Physics: Vernier calliper, Ohm’s law
• Chemistry: Titration, one salt analysis
• Biology: Microscope work, one temporary mount

________________________________________

Mistake #4: Ignoring Viva Preparation 🗣️
Problem: Students focus only onthe  file, forget that the viva is 8-12 marks

Why this fails:

• Blank during viva
• Lose 5-8 marks easily (40% of practical marks!)
• Can’t explain experiments in the file
• Examiner doubts whether you made the file yourself

Solution: Prepare 50 common Viva questions for your subject

• Go through the theory chapters
• Understand the principle of each experiment
• Practice answering in 2-3 sentences
• Revise formulas and definitions

________________________________________

Mistake #5: Poor File Presentation 📄
Problem: Messy handwriting, no diagrams, pages falling out, torn papers

Why this fails:

• Examiner’s first impression is negative
• Loses marks in file checking (1-2 marks gone)
• Shows carelessness
• Difficult to read and evaluate

Solution:

• Use quality A4 ruled sheets
• Write neatly in blue/black pen
• Proper binding (spiral or stitched)
• Clean diagrams with labels
• No overwriting or cutting

________________________________________

Mistake #6: Missing Compulsory Components 📝
Problem: No index page, no certificate page, no teacher signatures

Why this fails:

• File considered incomplete
• Marks deducted
• May be rejected at some centres
• Shows poor understanding of requirements

Solution: Use this checklist before submission:

• Cover page with subject name, code, name, and enrollment
• Certificate page (signed by teacher)
• Index with experiment names and page numbers
• All experiments with complete information
• The teacher’s signature on each experiment
• Proper binding

________________________________________

Mistake #7: Not Attending Practical Classes 🏫
Problem: Students never visit the study centre for practical sessions

Why this fails:

• Don’t know basic apparatus handling
• Never saw the real setup
• Theoretical knowledge only
• Panic during the exam

Solution: Attend at least 2-3 practical sessions at your study centre

• See the apparatus in real
• Watch teacher demonstrations
• Clear doubts about procedures
• Build confidence

________________________________________

Mistake #8: Submitting a Printed File Without Confirmation
Problem: Students print the entire file, but the centre rejects the printed files

Why this fails:

• File rejected on exam day
• Panic and stress
• No backup handwritten file
• May have to skip the exam

Solution:

• Always check with your AI/Study Centre BEFORE printing
• Call and confirm: “Do you accept printed practical files?”
• If unsure, go handwritten (100% safe)
• Or use our handwritten file service

________________________________________

Mistake #9: Incomplete Experiments
Problem: Writing only 5-6 experiments instead of the required 10

Why this fails:

• File considered incomplete
• Marks were deducted heavily in file checking
• Shows a lack of effort
• The examiner may refuse to evaluate

Solution:

• Check syllabus – minimum 10 experiments for most subjects
• Include all mandatory experiments
• Don’t skip complex experiments (the examiner may give an easy alternative on exam day)
• Complete file = higher chances of full marks

________________________________________

Mistake #10: Not Reading the NIOS Lab Manual
Problem: Students follow random formats from the internet

Why this fails:

• Format doesn’t match NIOS requirements
• Missing important sections
• The observations table structure is wrong
• Doesn’t align with the NIOS syllabus

Solution: Download the official NIOS lab manual for your subject

• Available free on the NIOS website
• Follow the exact format given
• Include all sections as per the manual
• Use prescribed observation tables

Frequently Asked Questions (FAQs)

General Questions

Q1: Which NIOS subjects have practical exams in Class 10?
Answer: Mathematics (211), Science & Technology (212), Home Science (216), Painting (225), Data Entry Operations (229), and Indian Knowledge Tradition subjects (245-248, 285) have practical exams in Class 10.

________________________________________

Q2: Which NIOS subjects have practical exams in Class 12?
Answer: Physics (312), Chemistry (313), Biology (314), Computer Science (330), Geography (316), Home Science (321), Painting (332), Data Entry (336), Environmental Science (333), Physical Education (373), Mass Communication (335), Library and Information Science (339), and Indian Knowledge Tradition subjects have practicals in Class 12.

________________________________________

Q3: Can I fail in NIOS just because of the practical?
Answer: Yes, especially in Class 12. For Class 12, you must score at least 33% in both theory and practical separately. If you fail the practical (below 33%), you fail the entire subject, even if your theory score is excellent. For Class 10, passing is based on aggregate (theory + practical + TMA combined 33%), but a low practical score still hurts your percentage badly.

________________________________________

Q4: How many experiments are mandatory in the NIOS practical file?
Answer:
• Science subjects (Physics/Chemistry/Biology): Minimum 10 experiments
• Mathematics (Class 10): 10 activities out of 20 available
• Geography: 15 practicals
• Computer Science: Minimum 10 programs
• Other subjects: Usually 10 practicals/activities
Always check your subject’s official NIOS lab manual for exact requirements.

________________________________________

Q5: Can I submit a printed NIOS practical file?
Answer: It depends on your AI (Accredited Institution/Study Centre). Most centres prefer handwritten files. Some centres accept printed files with handwritten observations and diagrams. Always confirm with your AI before printing. Call your study centre and ask specifically: “Do you accept printed practical files or only handwritten?” Handwritten is 100% safe everywhere.

________________________________________

Q6: When are NIOS practical exams held?
Answer:
• April 2026 session: Practical exams in January-February 2026 (before theory exams)
• October 2025 session: Practical exams in August-September 2025 (before theory exams)
Practical exams are always held 1-2 months BEFORE theory exams. Don’t confuse the dates!

________________________________________

Q7: Is the NIOS practical exam easier than the CBSE?
Answer: Yes, generally, NIOS practical exams are considered easier than CBSE because:
• You choose which 10 experiments to write (flexibility)
• The external examiner is usually lenient
• Viva questions are basic and straightforward
• Marking is generous
• Format requirements are simple
• You can use ready-made files (most students do)

________________________________________

Q8: Can I buy ready-made NIOS practical files?
Answer: Yes! Thousands of NIOS students use ready-made practical files every year. As long as the file meets NIOS format requirements, is complete, and has proper observations, examiners accept it. We’ve sold 10,000+ files with 100% acceptance rate. Just make sure you understand the experiments for the viva questions.

Practical Exam Process Questions

Q9: What happens if I don’t submit the NIOS practical file?
Answer: If you don’t submit a practical file:
• You get ABSENT in that subject
• Your theory exam marks won’t be counted
• You’ll have to reappear for both theory AND practical in the next session
• Complete waste of all your preparation
Even if you can’t attend the practical exam due to an emergency, try to submit the file at least.

________________________________________

Q10: How are NIOS practical marks calculated in the final result?
Answer: Practical marks are added directly to theory marks. For example:
• Theory scored: 65/80
• Practical scored: 18/20
• Final marks shown on marksheet: 83/100
• No separate marking – combines into total
For subjects with TMA (20 marks), the total becomes 120, which is then scaled to 100 for the final marksheet.

________________________________________

Q11: Can I do the NIOS practical at home?
Answer: No, you cannot do the practical exam at home. You MUST attend the practical exam at the designated NIOS exam centre with an external examiner. However, you can complete your practical file at home and submit it at the centre on exam day.

________________________________________

Q12: What is the pass percentage for the NIOS practical?
Answer: You need a minimum 33% in practical to pass. Examples:
• If practical is 20 marks → need minimum seven marks (33% of 20)
• If practical is 40 marks → need minimum 14 marks (33% of 40)
• If practical is 15 marks → need minimum five marks (33% of 15)
Note: For Class 12, this 33% must be submitted separately. For Class 10, it’s part of the aggregate.

________________________________________

Q13: Are NIOS practical files checked strictly?
Answer: No, NIOS practical file checking is much more lenient than CBSE. Examiners mainly check:
• File completeness (all required experiments present)
• Basic neatness (readable handwriting)
• Diagrams included
• Teacher signature present
• Proper format followed
Most students with reasonably good files score 3-4 out of 4 marks in file checking. Examiners understand NIOS students have time constraints.

________________________________________

Q14: Can I use the same practical file for the re-exam?
Answer: If you’ve failed and are reappearing, you CAN submit the same practical file if:
• It’s complete and well-maintained
• You got it signed by the examiner in the previous attempt (very important)
• No significant changes required
• File is still in good condition (not torn/damaged)
However, if your file was one of the reasons for your low marks, it’s better to make a new, improved file.

________________________________________

Q15: How long does the NIOS practical exam take?
Answer:
• File submission and checking: 30 minutes
• Your turn for experiment: 30-45 minutes
• Viva voce: 5-10 minutes
• Total time at centre: 1-2 hours (including waiting time)
You don’t spend the entire 3 hours. The 3-hour duration mentioned is for the overall exam session, not per student.

________________________________________

Documents & Requirements Questions

Q16: What documents should you carry for the NIOS practical exam?
Answer: Mandatory documents:
• Practical exam admit card/hall ticket (2 printouts)
• Practical file (bound and complete)
• Photo ID proof (Aadhaar/Passport/DL/Voter ID)
• Black/blue pens (2-3)
• Pencil, eraser, ruler for diagrams
• Calculator (for science/maths subjects)
• Recent passport-size photos (2 copies)
Optional but recommended: Water bottle, pen drive (for computer practicals)

________________________________________

Q17: Can I change my NIOS practical exam centre?
Answer: Usually, no, the centre is assigned based on your AI registration. But in genuine emergency cases (medical, family emergency, natural disaster, etc.), you can request the NIOS regional centre. You must:
• Apply at least 15 days before the exam
• Provide a valid documented reason
• Get approval from the Regional Director
• Pay any applicable fees
Success rate is low, so don’t count on it. Plan to attend the assigned centre.

________________________________________

Q18: Do NIOS practical marks count for university admission?
Answer: Yes, absolutely! Your final NIOS marksheet shows total marks (theory + practical combined). All universities, colleges, and competitive exam authorities accept it exactly like CBSE/state board marksheets. Practical marks can actually boost your percentage significantly, which helps in:
• College admissions
• Scholarship eligibility
• Job applications
• Competitive exam cut-offs

________________________________________

Q19: Is there negative marking in the NIOS practical?
Answer: No, there is no negative marking in NIOS practical exams. You can only gain marks, not lose them. This is why it’s easier to score in practicals:
• Wrong answer in viva = 0 marks for that question (not negative)
• Experiment mistake = marks for correct steps still given
• File errors = marks deducted only for that section
So always attempt everything – you won’t lose marks!

________________________________________

Q20: Can I write the NIOS practical file in Hindi?
Answer: Yes, if you’re appearing for the Hindi medium exam, you can write your practical file in Hindi. However:
• Scientific terms, formulas, and chemical equations should remain in English/standard scientific notation
• Apparatus names usually remain in English
• Observations can be in Hindi
• Procedure and theory in Hindi is fine
Check with your AI/study centre to confirm language policy.

________________________________________

Q21: Are ready-made practical files legal/allowed?
Answer: Yes, using ready-made practical files is entirely legal and widely practised. There’s no NIOS rule against it. You’re simply using reference material to prepare your file. Thousands of students use commercial guides, solved papers, and sample files – practical files are no different. As long as the content is accurate and meets format requirements, it’s perfectly acceptable.

________________________________________

Q22: Will the examiner know I bought the file?
Answer: No. Our files are designed to look like student-made files, not commercial products. We:
• Use normal student-style handwriting (not fancy)
• Include realistic observations (not perfect)
• Follow standard NIOS format
• Don’t put any company branding
Examiners see hundreds of files – they can’t tell who made it as long as the quality is good.

________________________________________

Q23: What if the examiner asks me to experiment not in my file?
Answer: The examiner will usually give you an experiment from your file only, because that’s what you’ve studied. But if they provide a different experiment:
• Stay calm, don’t panic
• Ask the examiner to explain what to do
• Do your best with the knowledge you have
• Examiners are understanding and may guide you
• Viva questions will still be based on your file experiments
This rarely happens, but be mentally prepared.

________________________________________

Q24: Can I get a refund if I am not satisfied?
Answer: Yes, we offer a money-back guarantee with conditions:
• PDF format: Refund within 24 hours if the file has missing experiments or the wrong format
• Handwritten format: Refund if file is damaged, incomplete, or significantly different from description
• No refund if you changed the content and then got rejected
• No refund after exam date has passed
Contact us immediately if you have any issues – we’ll resolve it.

________________________________________

Q25: How do I get a teacher’s signature on the bought file?
Answer: Simple process:

• Take the file to your AI/study centre
• Meet your subject teacher
• Show the file and say, “I’ve completed my practical file, please check and sign”
• Most teachers will quickly review and sign (they know students use references)
• If the teacher asks questions, explain experiments confidently (study the viva questions we provide)

99% teachers sign without issues. They check if the file is complete and in the proper format.
