NEET Physics preparation: how to score in 45 questions

By the PrepMatic team · Updated 8 Oct 2026 · 8 min read

NEET Physics is 45 questions for 180 marks, a quarter of the paper, and it is the section where most students lose marks to slow calculation and small slips rather than to missing concepts. The reliable way to prepare is to learn every chapter in three layers (concept, then formula with its conditions, then numericals of rising difficulty) and to work in a priority order: mechanics and the electricity-magnetism chain first, optics and modern physics next, small units fitted around them.

What NEET Physics actually tests

The NMC syllabus lists 20 Physics units, from Physics and Measurement to Experimental Skills (the full list is on the NEET syllabus page). Most questions are an NCERT-level idea applied through a standard formula in one or two steps. A smaller share are longer, multi-step numericals. Recent papers have also included statement-based questions, graph-reading questions and match-the-columns items, so a formula memorised without its meaning will not carry you.

Because a wrong answer costs 1 mark and a right one earns 4, a rushed Physics numerical that ends in a wrong option wastes both the time and a mark. Accuracy and a clean method matter more than speed on any single question; speed comes from method.

Unit groups and a sensible order

NMC lists units, not classes. The Class 11 and Class 12 column below is the usual NCERT mapping, which is our grouping and not an NMC rule. The order is a working order for study, not official weightage; for how much each area tends to be asked, see NEET high weightage chapters.

The electricity-magnetism chain is the most connected part of the syllabus: electrostatics leads to current electricity, then magnetism, then induction and AC. Study it in that order and each chapter makes the next easier. In mechanics, kinematics leads to laws of motion, then work-energy, then rotation and gravitation. Running one mechanics chapter and one electricity chapter side by side each week keeps you from feeling that all of Physics is a single block.

The NMC list added Experimental Skills as its own unit. It is small, and it is the kind of unit that is easy marks for the student who has handled the instruments and hard marks for the one who has only read about them. Check the exact experiment list in the NMC PDF.

The concept, formula, numerical method

For every chapter, do these four things in order.

1. Concept. Read the NCERT text and write the idea in one plain sentence with no symbols. If you cannot, you have not understood it yet.
2. Formula with conditions. Derive each key formula once. Write down its units and the condition under which it holds. v² = u² + 2as is for constant acceleration only; Gauss's law is useful only with symmetry.
3. Numericals in three levels. Direct substitution (NCERT in-text examples), then two-step problems, then exam-level MCQs from a chapter-wise book or past papers.
4. Check before you tick. Check units, check an extreme case, and check the sign. This habit alone removes a large share of careless errors.

Worked example: cross-check with a second method

A 5 kg ball is dropped from a height of 20 m. Take g = 10 m/s². Find its speed and kinetic energy just before it hits the ground.

• Kinematics: v² = 2gh = 2 × 10 × 20 = 400, so v = 20 m/s. Kinetic energy = ½ × 5 × 20² = 1000 J.
• Energy: the potential energy lost is mgh = 5 × 10 × 20 = 1000 J.

The two routes agree, so the answer is safe. In an exam you will not always have time for both, but in practice sessions, solving each problem two ways builds the instinct for choosing the faster route.

Formulas to know cold

This is a starter sheet, not the whole syllabus. The right-hand column is the condition most often forgotten.

Common weak spots, and how to fix them

• Sign convention in optics. Measure distances from the optical centre, with the direction of incident light as positive. Example: an object 30 cm in front of a convex lens of focal length +20 cm has u = −30 cm. Then 1/v = 1/20 − 1/30 = 1/60, so v = +60 cm, a real image on the far side, and magnification v/u = −2, inverted and twice the size. Do five of these until the signs feel automatic.
• Units and prefixes. Centimetres in a formula that needs metres, grams where kilograms are needed, eV mixed with J. Write units on every line of a calculation.
• Circuits. Redraw the circuit with labelled nodes before simplifying. Look for a balanced Wheatstone bridge and for symmetry.
• Graphs. Ask what the slope and the area under the curve mean for that pair of axes. Many v-t, F-x and P-V questions are solved this way without any algebra.
• Moment of inertia. Know the standard values, the parallel-axis theorem (I = I(cm) + Md²) and that the perpendicular-axis theorem applies only to flat bodies.
• Approximations. For small x, (1 + x)ⁿ ≈ 1 + nx. It makes several numericals much faster.
• Experimental Skills. Practise least count, vernier constant and zero error with actual numbers, not just definitions.

Books and practice beyond NCERT

NCERT is the base for the concepts (see how to read it in NCERT for NEET), but its problems are fewer than the exam demands. Add one concept-depth book and one chapter-wise MCQ source, and avoid collecting more. Many students use HC Verma's Concepts of Physics for depth, working selected problems rather than every one, together with NCERT Exemplar problems and a chapter-wise objective book such as DC Pandey's series. Stay with one set of each rather than switching mid-chapter.

A weekly rhythm that works for most students:

• Four or five days: a new chapter, with a concept session and a numerical session on different days.
• One day: past-paper questions on chapters you have completed. See NEET previous year question papers.
• One day: a timed set of 45 Physics questions, the same count as the real section, then a written error log.

Physics fades fastest when you stop practising it. Revisit finished chapters on the cycle in the NEET revision strategy, and take full papers from the mock test guide once most units are done.

Using PrepMatic for Physics

PrepMatic's free assessment is about 15 untimed multiple-choice questions. Its result shows whether Physics is among your weakest subjects, at subject level rather than chapter level, so you know where to start. The study plan then turns your exam date, daily hours and study days into a Today view and a Roadmap, and you can take topic tests on what you have finished. For timed practice, build a custom mock by choosing the subject, number of questions, duration and difficulty, for example a Physics-only set, or let a mock be focused on your weak subjects.

Frequently asked questions

How many chapters are in NEET Physics?

The NMC syllabus lists 20 Physics units. NMC lists units, not NCERT chapters, so the number of textbook chapters you study will be different. The units run from Physics and Measurement to Experimental Skills.

Is NCERT enough for NEET Physics?

NCERT is essential for concepts and derivations, but it has relatively few practice problems. Most students add a chapter-wise MCQ book and past-paper questions for numerical practice. NCERT Exemplar problems are a good bridge between the two.

Which Physics chapters are most important for NEET?

Mechanics, the electricity and magnetism chapters, optics and modern physics tend to carry the most questions in recent papers, but the pattern is unofficial and shifts yearly. See the tiered table in high weightage chapters and do not skip the small units.

Is Experimental Skills part of the NEET syllabus?

Yes. The NMC unit list includes Experimental Skills as the 20th Physics unit. Check the NMC syllabus PDF for the exact experiments listed.

How do I improve my Physics score if I make many calculation errors?

Write units on every line, solve each practice problem a second way where one exists, and keep an error log that labels each mistake as concept, formula, calculation or time. Fix the most frequent label first.
