CBSE senior secondary science
CBSE Class 12 Physics (subject code 042) is a 70-mark, three-hour theory paper across nine units, from electrostatics to semiconductor devices, with a further 30 marks from a practical examination run in school. Edunest matches your child with a physics tutor for live one-to-one lessons online that build full board answers and the problem-solving habits JEE and NEET test.
Lessons run on Qatar time and fit the Sunday-to-Thursday timetable, follow the NCERT chapters in your school's order, and keep the practical record and viva in view from the start.
What we cover
The CBSE syllabus groups fourteen NCERT chapters into nine units, and the board weights them in five blocks. Each module shows its block's marks and where learners usually drop them.
Coulomb's law and electric fields, Gauss's theorem for a long wire, a plane sheet and a thin spherical shell, then potential and capacitors with dielectrics. Learners slip on field directions and on choosing a sensible Gaussian surface.
Drift velocity, resistivity and its dependence on temperature, internal resistance, and circuits solved with Kirchhoff's rules and the Wheatstone bridge. Marks go when loop signs drift or when emf is confused with terminal potential difference.
The Biot-Savart law for a circular loop, Ampere's law for a long wire, forces on charges and currents, and converting a moving coil galvanometer into an ammeter or voltmeter. Direction rules in three dimensions cause most lost marks.
Faraday's and Lenz's laws, self and mutual induction, then RMS values, reactance, impedance and the series LCR circuit drawn with phasors, resonance and power factor. Phasor diagrams and the direction of induced current trouble many learners.
Displacement current and the spectrum, then mirrors, lenses, prisms, total internal reflection and optical instruments, followed by Huygens' principle, Young's double slit and single-slit diffraction. Sign conventions in the mirror and lens formulae are the commonest trap.
The photoelectric effect and Einstein's equation, de Broglie waves, the Bohr model of hydrogen, mass defect, binding energy per nucleon, fission and fusion. Learners lose marks reading stopping-potential graphs and converting between electronvolts and joules.
Energy bands at a qualitative level, intrinsic and extrinsic semiconductors, the p-n junction, diode behaviour in forward and reverse bias, and the diode as a rectifier. A short unit where exact diagrams and labelled graphs earn quick marks.
Experiments from Section A (resistivity, metre bridge, galvanometer) and Section B (mirrors, lenses, prism, diode), activities and a project. The record must hold at least eight experiments, six activities and the project report.
Content that NCERT marks as excluded for 2026-27 is not assessed, so the tutor checks the current list before setting any revision.
How lessons run
Class 12 physics moves quickly, with pre-boards, practicals and entrance registrations packed into one year. Lessons follow a steady cycle that fits the Qatar school week.
Step 1
Lesson one opens with a short set of problems across fields, circuits and optics, plus a look at recent school tests. Class 11 tools such as vectors and basic calculus are checked too, because Class 12 derivations lean on them.
Step 2
The tutor maps the NCERT chapters to your child's school timetable, pre-board dates and practical week. Lessons take fixed slots once classes end on school days, or over the Friday-Saturday weekend, always on Qatar time (UTC+3).
Step 3
Each topic moves from the idea to the derivation the board expects, then to worked numericals and a case-based question. Diagrams are drawn live on a shared whiteboard, and your child explains each step back before moving on.
Step 4
Before the school's practical examination, the tutor walks through each experiment in the record: aim, circuit or ray diagram, observation table, graph, precautions and sources of error. Short mock viva questions build calm, clear spoken answers.
Step 5
Timed papers follow the five-section board pattern, with no calculator. Answers are marked step by step, recurring errors go into a running log, and parents get a brief note on progress.
In Ramadan, the timetable shifts to match the official hours announced for that year.
The exam
CBSE sets the board paper and the practical scheme. JEE (Main) and NEET (UG), run by the National Testing Agency, draw on the same Class 12 physics in a faster, objective question style.
Exam board
Central Board of Secondary Education (CBSE) · 042
Sets the syllabus and the board examination; NCERT Physics Part I and Part II are the prescribed textbooks.
Exam board
JEE (Main) Paper 1, National Testing Agency
Physics was a third of the 2026 paper: 25 questions (20 multiple-choice, 5 with a numerical answer) worth 100 marks, taken on computer.
Exam board
NEET (UG), National Testing Agency
The 2026 bulletin set 45 physics questions out of 180, four marks each with one deducted per wrong answer, in a pen-and-paper test.
33 compulsory questions in five sections, from one-mark items to five-mark long answers.
How a tutor helps
The tutor drills the five-mark derivations and the case-study questions, and trains your child to set out numericals with units and clear steps, because board marking schemes award marks for each step.
Two experiments (7 marks each), record 5, one activity 3, project 3, viva 5.
How a tutor helps
Online lessons prepare everything around the bench work: the theory behind each experiment, tables of readings, graphs, precautions and sources of error, with mock viva rounds before the day.
CBSE-affiliated schools in Qatar follow the board's annual cycle: school-based practicals first, then the written papers. Dates for 2027 come from CBSE's own date sheet; the latest cycle ran as follows.
CBSE grades Class 12 on a 9-point positional scale. Passed candidates are ranked and split into eighths, from A1 for the top eighth down to D2; a grade of E means essential repeat.
What we look for in a tutor
Each point below applies to every tutor we match with a Class 12 physics learner.
A strong physics background with the mathematics behind it, so derivations and numericals are explained from first principles.
Knows the 2026-27 syllabus, the NCERT chapters, the excluded content and how board marking schemes allot step marks.
Has taught Class 12 learners through board papers and understands how JEE (Main) and NEET (UG) physics questions differ in style.
Understands the Class 12 experiments and activities well enough to rehearse readings, graphs, precautions and viva answers with your child.
Draws field lines, circuits and ray diagrams live, and checks understanding by asking your child to explain each step aloud.
Works to child-safeguarding standards with teenage learners, is comfortable with a parent watching, and updates the family regularly.
Common difficulties
Five problems that surface again and again during board preparation.
Reading a problem, choosing the right law and handling units are separate skills from understanding the theory.
How a tutor helps
The tutor teaches a fixed routine: list the knowns, sketch, choose the principle, solve with symbols, then substitute. Your child practises it on graded sets until it becomes automatic.
CBSE is setting more questions in real-life situations, so a learned-by-heart derivation breaks when the setup shifts.
How a tutor helps
Each derivation is rebuilt from its starting assumption, with the physical meaning of every step discussed. Then the tutor changes one condition and asks your child to adapt the argument.
The Cartesian sign convention feels arbitrary until a learner sees why distances are measured from the pole or optical centre.
How a tutor helps
Every problem starts with a labelled ray diagram and a written sign check. The tutor sets mixed mirror and lens questions until the convention is applied without hesitation.
The record needs at least eight experiments and six activities, and viva questions probe theory, procedure and sources of error.
How a tutor helps
The tutor reviews the record experiment by experiment, explains the theory behind each reading and runs short mock vivas, so your child answers calmly in their own words.
Board answers reward full written steps, while entrance tests reward speed and accuracy on objective questions with negative marking.
How a tutor helps
The plan puts board depth first for each chapter, then adds timed objective sets on the same topic, so a single round of study serves both goals.
