Plus Two Physics practical: tips, marking scheme, and step-by-step checklist

Main purpose

Advice for students preparing for the Plus Two (12th) Physics lab exam: how the exam normally runs, what to write and how to present answers to secure full marks, and where to get revision videos and help.

Key points / lessons

Official demonstration videos are available from the Education Board (YouTube playlist). The presenter’s channel (Eduport Plus Two) links that playlist in the comments and has its own helpful videos (e.g., a popular screw-gauge video).
Join the presenter’s free WhatsApp community for daily aims, theory summaries and likely viva questions.
Many students can score full marks (40/40) by following the correct format and practising standard experiments carefully.
Typical lab exam format:
- You get a hidden question paper and choose one of two experiments.
- Each experiment carries 18 marks; two experiments → 36 marks.
- Record book adds 4 marks → total 40 marks.
- Viva contributes 1 mark per experiment.
Focus on doing the standard experiments well: screw gauge, simple pendulum / oscillation method of helical spring, refraction through a prism, lens/mirror focal-length methods, Ohm’s law circuits, etc. The channel will add videos for missing experiments.

Step-by-step checklist to follow in the exam

Before exam day — resources & preparation
- Watch the Education Board’s complete lab videos and the Eduport videos (playlist link in comments on the channel).
- Join the WhatsApp community for daily theory and expected viva questions.
- Practise the common school experiments repeatedly (screw gauge, pendulum, lens/mirror methods, Ohm’s law, spring oscillation, prism refraction).
What to bring
- Record book and hall ticket.
- Pencil, pen, eraser, ruler.
- Personal calculator (don’t rely on borrowing).
- Any allowed measuring tools as per your school rules.
On receiving the question paper / answer sheet
- Note which experiment is asked and write the exact question at the top of the answer sheet.
- Write the Aim clearly.
Theory / Principle (important: carries marks)
- Write a short, relevant theory/principle — include only essential equations.
- Example (simple pendulum):
  
  T = 2π √(l/g) ⇒ T² = (4π² l) / g ⇒ g = (4π² l) / T²
- Avoid long unrelated theory; stick to what’s needed for the experiment and derivation.
Apparatus & Diagram
- List apparatus.
- Include a neat circuit diagram for electrical experiments or a clear apparatus sketch.
- For optics: draw the ray diagram of image formation (concave/convex lens or mirror).
Setting up and performing the experiment
- Set up the apparatus exactly and neatly.
- Follow the prescribed procedure and take accurate readings — neatness and correct procedure are marked.
- Be careful and methodical; careless work invites queries and lost marks.
Tabular column & observations
- Draw a clear table with properly labeled columns (include units).
- Use correct independent (x) and dependent (y) variables when preparing for graphs.
Graphs & data analysis
- Plot the required graph: label axes, include units, choose correct scales.
- Show how you obtain slope/intercept if required and how you use those values to compute the required quantity.
- Clearly indicate which variable is on x and which on y.
Calculations & Units
- Show intermediate calculations cleanly.
- Convert measured values to SI units before final calculations (e.g., mm or cm → m).
- Final result must be in SI units.
- Watch powers of ten and unit conversions.
Conclusion / Result - State the final result with unit and a short conclusion. - If required, show percentage error or uncertainty calculation.
Viva / Short questions - Prepare for simple viva questions (usually 1 mark each). - If you know the experiment you will likely get the mark — don’t over-stress the viva.
Record book - Keep your year-long record accurate and neat — it accounts for 4 marks.

Practical tips / reminders

Stick to the exact method asked. For lens experiments, do only the specified method (e.g., u–v method, 1/v vs 1/u, or distant object method) rather than doing everything.
For screw gauge: measure diameters carefully and convert to meters before the final answer.
For pendulum: show a succinct derivation and, if required, plot T² vs l and use the slope to compute g.
Don’t write overly long or irrelevant theory — be concise and correct.
Confidence and preparedness reduce delays and prevent losing marks for trivial reasons.

Marking scheme (as described in the video)

Theory / principle: about 5 marks.
Setting up / performing experiment & neatness: approximately 6 marks (presenter’s estimate).
Experiment total: 18 marks per experiment → 36 for two experiments.
Record book: 4 marks.
Total: 40 marks.
Viva: 1 mark per experiment (short/simple question).
