A Physics paper mostly tests three things: derivations, numericals and reasoning questions. Derivations slip away around the third step. Numericals lose marks on units.
Reading a derivation ten times does not help much. Rebuilding it from a few key steps does. These prompts make an AI chat hold back the full answer so that you do the rebuilding.
One rule before you start. AI chats get facts wrong sometimes. If an answer does not match your NCERT or board textbook, the textbook wins.
Level 1: Derivations
Level 1 · Derivation skeleton
Give me the derivation of [DERIVATION NAME] from Class 12 Physics as a skeleton: only the starting point, the key steps in one line each and the final result. No full working. I will fill in the working myself.
Level 1 · Fill the missing steps
Write the derivation of [DERIVATION NAME] step by step, but leave every second step blank. Show it one step at a time and let me write the missing step. Check me each time.
Level 2: Numericals
Level 2 · Numerical coach
I am solving this numerical: [TYPE THE QUESTION]. First ask me to list the given values with units and what I need to find. Then ask me which formula fits. Give a hint only if I am stuck. Do not solve it for me.
Level 2 · Unit police
Here is my solution to a numerical: [TYPE YOUR STEPS]. Check only two things: units and significant figures. Show me every place where a unit is missing or wrong.
A right number with a missing unit can still cost you marks.
Boss level
Boss level · Give reason
Ask me 5 reasoning questions from the chapter [CHAPTER NAME] of the type "give reason" or "what happens if". Ask one at a time. After each answer, tell me the key physics idea the examiner wants to see.
Boss level · Formula map
Make a formula map for the chapter [CHAPTER NAME]: every formula, the SI unit of each quantity and which other formula it connects to. Then test me on the units.
Warm-up questions
Answer in your head, then check.
Question
A wire of resistance 10 Ω carries a current of 2 A. Find the potential difference across it.
V = IR = 2 × 10 = 20 V.
Question
What is the SI unit of capacitance?
The farad (F). One farad is one coulomb per volt.
Question
Why is a dielectric placed between the plates of a capacitor?
A dielectric increases the capacitance, so the capacitor stores more charge at the same potential difference.

A simple routine
Pick two derivations and three numericals a day. Use the skeleton prompt in the morning and write the same derivations from memory at night. The ones you cannot finish go on tomorrow’s list.
