Ajay Vatsyayan Classes provides a one-to-one CBSE Class 12 Physics home tutor in Gurugram, at your home or in live online classes, for the 2026–27 board exam. CBSE Physics (042) has a 70-mark theory paper of 3 hours and 30 practical marks. The tutor plans the year around those marks, the 33-question paper design and the practical record. You meet the tutor in a free demo class before you decide.

We have taught in Gurgaon for 12+ years, with 25,000+ students, 500+ verified tutors and families from 50+ Gurgaon schools. This page covers the board paper itself. Facts come from CBSE's 2026–27 Physics curriculum and Sample Question Paper on cbseacademic.nic.in, checked on 30 September 2026.

CBSE Class 12 Physics 2026–27: units and marks

The theory paper covers nine units across 14 NCERT chapters. CBSE gives marks to sets of units, not to single chapters, and the largest set is electromagnetic waves with optics, at 18 marks.

What the syllabus limits

• Energy stored in a capacitor: "no derivation, formulae only".
• Solenoid and bar magnet: the straight solenoid, the bar magnet as an equivalent solenoid, its field on the axis and perpendicular to it, and the torque on it are all qualitative only.
• Wave optics: for Young's double slit, the fringe width is "final expression only"; single-slit diffraction is qualitative.
• Atoms: hydrogen line spectra are qualitative, but the radius, velocity and energy in the nth Bohr orbit are included.
• Semiconductors: this chapter stops at the p-n junction diode and the diode as a rectifier.
• NCERT exclusions: content marked as excluded in the NCERT textbooks for 2026–27 will not be assessed in the board exam.

The question paper design: 33 questions, five sections

The 2026–27 Sample Question Paper has 33 compulsory questions in five sections, and says the design is unchanged from last year. Calculators are not allowed, so numericals are set to be worked out by hand.

The curriculum also fixes the thinking levels. About 38% (27 marks) is remembering and understanding, 32% (22 marks) is applying, and 30% (21 marks) is analysing, evaluating and creating. So almost a third of the paper cannot be answered from memory alone.

From our tutors: most lost marks are not in the hard questions. They go on two-mark answers with no formula written, numericals with no units, and ray diagrams with no arrows. CBSE's marking scheme gives half marks for steps, so we mark every practice answer against it. That way students learn where the step marks are before the pre-boards.

Practicals and the investigatory project: 30 marks

The 3-hour practical exam carries almost a third of the subject total, and steady work through the year secures most of it.

• Record: at least 8 experiments (4 from each section), at least 6 activities (3 from each section), and the project report.
• Section A (electricity): experiments include the metre bridge, a galvanometer's resistance by half-deflection, and converting a galvanometer into a voltmeter or ammeter.
• Section B (optics and devices): experiments include focal lengths of mirrors and lenses, minimum deviation in a prism, refractive index, and the p-n junction diode's I–V curve.

The viva is where theory meets the lab. A student who can explain why the metre bridge is most accurate near its middle gains easy marks. For project ideas, see our physics project ideas guide.

How the board paper differs from JEE and NEET

The Class 12 chapters are shared, but the exams test them differently. The board rewards written explanation, derivations, diagrams and practical work. JEE Main and NEET reward fast, accurate answers on material from both Class 11 and Class 12.

Sources: the JEE (Main) 2026 and NEET (UG) 2026 Information Bulletins on jeemain.nta.nic.in and neet.nta.nic.in; check the current bulletin each year. Our guide to Class 12 board physics and JEE maps every unit against the JEE syllabus. For entrance support, see our JEE physics tutor in Gurgaon and NEET physics tutor in Gurgaon pages.

The chapters students usually find hardest

In our experience, five areas cause most of the trouble. None is hard because of the maths. Each needs a clear picture before the formulae make sense.

Dual Nature, Atoms, Nuclei and Semiconductors are shorter and more direct. Together they carry 19 marks, and they are a good place to secure marks late in the year.

From our tutors: a derivation is not learned until the student can write it without looking. Our students write one derivation from memory at the start of each session. By the final weeks, derivations are no longer a revision task.

Three worked board numericals

Board-style questions of the kind our tutors set, with numbers that need no calculator. We checked every answer by calculation.

1. Alternating current: a series LCR circuit

Question (3 marks): A series LCR circuit has R = 30 Ω, X_L = 80 Ω and X_C = 40 Ω, on a 200 V (rms) supply. Find the impedance, rms current, power factor and average power.

Z = √(R² + (X_L − X_C)²) = √(30² + 40²) = 50 Ω. I = V/Z = 200/50 = 4 A. cos φ = R/Z = 30/50 = 0.6. P = VI cos φ = 200 × 4 × 0.6 = 480 W (check: I²R = 16 × 30 = 480 W).
Answer: 50 Ω, 4 A, 0.6, 480 W. Common error: adding R, X_L and X_C directly instead of as phasors.

2. Galvanometer conversion

Question (3 marks): A galvanometer of resistance 50 Ω gives full-scale deflection at 2 mA. Convert it into (a) a 0–10 V voltmeter and (b) a 0–1 A ammeter.

(a) Series resistance R = V/I_g − G = 10/0.002 − 50 = 4950 Ω.
(b) Shunt S = I_gG/(I − I_g) = (0.002 × 50)/0.998 ≈ 0.10 Ω, in parallel.
Answer: 4950 Ω in series; about 0.10 Ω in parallel. This is also a Section A practical, so the idea is examined twice.

3. Ray optics: a lens, then a combination

Question (3 marks): An object is 30 cm from a convex lens of focal length 20 cm. (a) Find the image position and magnification. (b) A concave lens of focal length 60 cm is placed in contact. Find the power of the combination and the new image position.

(a) With u = −30 cm and f = +20 cm, 1/v = 1/f + 1/u = 1/20 − 1/30 = 1/60, so v = +60 cm and m = v/u = −2.
(b) 1/F = 1/20 − 1/60 = 1/30, so F = +30 cm and P = 100/30 ≈ +3.3 D. The object now sits at the focus: 1/v = 1/30 − 1/30 = 0, so the image is at infinity.
Answer: (a) real, inverted, 60 cm behind the lens, twice the size; (b) +3.3 D, image at infinity. Common error: taking the concave lens's focal length as +60 cm.

How a one-to-one tutor plans the year

The tutor plans backwards from three fixed points: the pre-boards, the practical exam and the theory paper. Each chapter then follows the school's teaching order. The shape below is common, and each plan is adjusted to the school calendar and the CBSE date sheet.

Most students have two or three sessions of 60–90 minutes a week, with a short timed set between sessions and a brief update to parents after each test. For all subjects, see our Class 12 tuition in Gurgaon page. Class 11 gaps are covered on our Class 11 tuition in Gurgaon page. ISC students can read our ISC Class 12 physics syllabus 2027 guide and see our ISC home tutors in Gurgaon page.

Can the same tutor help with JEE or NEET physics?

Yes. The tutor teaches the board chapter first, then adds entrance-level depth. Our NEET home tutors in Gurgaon page covers all three NEET subjects.
