Your practical file is due, the readings are in your rough notebook, and you want someone to look it over before your teacher signs it. AI can do that job well, as long as you give it the right job: checker, not writer.
Can AI check my practical file?
Yes, for the parts that follow rules, and marks ride on them. In the CBSE Physics curriculum for 2026-27, the Class 12 practical exam is out of 30 marks, and the practical record is worth 5 of them. The same document says the record must include at least 8 experiments and 6 activities "to be performed by the students", and a further 5 marks go to a viva on your experiments, activities and project.
That phrase is the line AI must not cross: your readings are evidence of what you did at the bench, and no AI knows what your ammeter showed on Tuesday.
What should AI check in the aim, table and result?
NCERT's Class 12 physics laboratory manual lists, among the reporting skills it expects, presenting the aim, apparatus, formula used, principle, observation table, calculations and result. It also says that reporting a result needs three things: the measured value, the expected uncertainty and the unit. That gives you a checklist an AI can test against:
Aim: does it say what is measured, with what apparatus, and by what method?
Observation table: does every column heading carry a unit? Are the least count and range of each instrument written down? Does each reading have as many decimal places as the instrument allows, and no more?
Result: is it written as value ± error with an SI unit, rounded so its significant figures match the error?
Ask for flags, not fixes. In a 2007 review in Review of Educational Research, John Hattie and Helen Timperley concluded that feedback is among the major influences on learning, but that the type of feedback and the way it is given make a difference to how well it works. Their review was not about AI, but the lesson carries over: a list of what to check keeps the thinking with you, which a polished paragraph you copy does not.
What prompt should I use?
Paste this, followed by your aim, table and result typed exactly as they are in your notebook:
"Check the aim, observation table and result of my physics practical against the NCERT lab manual format. Do not change, round, add or remove any reading. Do not write any section for me. List each problem as: section, what is missing or wrong, and a question I should answer to fix it. If a reading looks unusual, tell me, but do not suggest a different value."
Worked example: what does good AI feedback look like?
This is a made-up draft for the CBSE Class 12 experiment to determine resistivity by plotting a graph of potential difference against current.
The draft aim says "To find resistance." The table headings are just "V" and "I", with readings 0.5, 1.0, 1.5, 2.0, 2.5 and 0.10, 0.20, 0.31, 0.40, 0.50. The result says "R = 4.996003 ohm".
A useful AI reply looks like this:
Aim: the experiment asks for resistivity, but your aim says resistance. Which wire, and by what method? Consider "by plotting a graph of potential difference against current".
Table: headings need units, V (V) and I (A). What are the least count and range of your voltmeter and ammeter? Write them above the table.
Table: 0.31 A sits slightly off the line the other points make. Keep it. Did anything change during that reading? If so, note it under sources of error.
Result: six decimal places are more than your meters can support. Work out the error from the least counts, then round R to match and write it as value ± error in Ω.
Notice what it did not do: it did not change 0.31 to 0.30 or hand you a final value. You do the rounding, which the viva examiner may ask you to explain.
If a flag exposes a gap, such as why the significant figures of a result must match its error, Fermi's AI tutor can work out what you already know and teach through it, so the fix makes sense before it goes in your file.
How do I use AI on my record without breaking school rules?
Ask your teacher what is allowed first; schools differ on AI use.
Type from your notebook, and copy every fix back by hand.
If you used AI, say so. Our guide on how to mention AI use in a school project has sample lines.
Work in batches: complete your Class 12 practical file in batches and run the check once per batch.
The viva tests whether the record is really yours, so try rehearsing practical exam procedures with AI.
Tonight, pick one experiment, paste the prompt, and fix the flags in your own hand.
