📘 Get the Formula Sheet — ₹99
Chalo, seedhi baat — Class 12 Physics is not hard because the syllabus is impossible. It is hard because you have too much to remember, too little time, and no one has laid it all in one place where your eyes find a formula in three seconds flat.
That is what a proper formula sheet is for. Not a shortcut. A revision weapon. This guide gives you the full chapter-wise map of every Class 12 Physics formula you need for CBSE 2026-27 boards — the same map inside the NCERT Kaksha Physics Formula Sheet, made by IITians, NITians, and district toppers.
📌 What's in this guide
Why Class 12 Physics Formulas Decide Your Board Score
Look at the last five years of CBSE Class 12 Physics papers and one pattern jumps out: 40–50% of every paper is direct or one-step formula application. Numericals, "state and derive", MCQs, assertion-reason — all sit on the same foundation. Instant formula recall makes everything solvable. Shaky recall makes even easy questions eat 4–5 minutes each, and you run out of time.
The trap most students fall into: revising from the textbook. NCERT is essential for learning, but during revision, flipping 300 pages to hunt for the capacitance of a spherical capacitor is a productivity disaster. That is a job for one A5 sheet, not fourteen chapters of prose.
CBSE Class 12 Physics — Unit-Wise Marks Weightage (2026-27)
Based on the CBSE Class 12 Physics theory paper of 70 marks, here is how marks are distributed across the five units — the data that should decide where your revision hours go:
| Unit | Chapters | Marks |
|---|---|---|
| Electrostatics + Current Electricity | Ch 1–3 | 16 |
| Magnetism + EMI & AC | Ch 4–7 | 17 |
| EM Waves + Optics | Ch 8–10 | 18 |
| Dual Nature + Atoms & Nuclei | Ch 11–13 | 12 |
| Electronic Devices | Ch 14 | 7 |
| Total (Theory) | 14 chapters | 70 |
The takeaway: Optics (18 marks) and Magnetism/AC (17 marks) together carry exactly half the paper — 35 of 70 marks. In our 20+ years of teaching Physics at NCERT Kaksha, students who master the formula sets of these two units first see the fastest score jumps, because both are formula-dense and question patterns repeat year on year.

How to Use a Formula Sheet the Right Way
Sirf sheet khareedne se marks nahi milte. Yeh 4-step method is how our top-scoring students use it:
1. Read First, Highlight Second (Day 1)
Do not touch a marker on Day 1. Read every chapter's formulas end-to-end. This activates recall — you already know 70% of these from class.
2. Mark Your "Danger Zone" (Day 2)
Now highlight the 20% you keep forgetting — usually capacitor combinations, lens sign convention, Bohr's radius, and RC circuit expressions. This becomes your daily 10-minute drill.
3. Solve One PYQ Per Chapter, Sheet Open (Days 3–20)
Open a previous-year board paper. Solve one numerical per chapter with the sheet beside you. Your brain builds the association: "this question type → this row on the sheet." That is how instant recall is trained.
4. Two Cold-Passes Before Boards (Day 30 & Exam Morning)
One full cold-revision pass 30 days out. One final 20-minute pass on exam-day morning — the pass that saves your paper.
The Last-60-Days Countdown Plan
This is the exact routine our 90+ scorers run in the final two months:
Keep an "Error List" — the habit that saves 5+ marks
Maintain a separate page for only the mistakes you repeat — wrong units, a forgotten sign convention in Ray Optics, or the wrong expression for capacitor energy. In the final week before boards, read only this error list. This one habit routinely saves students 5–8 marks in the paper.
