A physics plan for NEET

Physics carries 45 of NEET's 180 questions: 180 marks, a quarter of the paper, the same as chemistry. For many candidates it is also the quarter with the lowest score. Biology rewards memory and close reading of NCERT. Physics rewards understanding and the ability to solve numericals quickly under pressure. That is why physics so often separates a good rank from an average one.

The good news is that physics responds to method. Most students who improve do it not by finding a better book, but by practising the same way every day for months. This guide sets out that method.

Why physics feels hard, and what actually fixes it

Three problems explain most weak physics scores:

• Concepts learnt as formulas. A student who memorises v² = u² + 2as without the condition "constant acceleration" will apply it where it does not hold.
• Too little practice. Physics is a skill. Reading solutions is not the same as solving questions.
• Slow recognition. In the hall, the time goes on working out what kind of question it is. Recognition comes only from volume.

The fixes follow directly: learn each formula with its conditions, solve questions daily, and solve enough of each type that you recognise it at once.

The syllabus in blocks

The NMC syllabus has 20 physics units. Grouped into blocks, they look like this:

NEET papers draw from across the whole syllabus, so there is no safe chapter to drop. Some chapters give better returns for the time: modern physics and semiconductors are shorter and more formula-driven, while mechanics and electricity take longer but also underpin other chapters.

How to study one chapter: a five-step loop

1. Read the NCERT chapter with a notebook. Follow each derivation and write down its idea in one line, even if you will not reproduce the whole thing. For example: "equations of motion come from the area under a straight-line v–t graph."
2. Solve the NCERT examples yourself before reading the solution. Then do the exercises.
3. Build the formula page for the chapter (see below).
4. Solve 40 to 80 graded questions: easy ones first for method, then previous-year NEET questions for level.
5. Log every mistake in an error book: the question, what went wrong (concept, calculation, misread), and the correct idea in one line.

Go back to step 1 only for the parts the error book shows you did not understand.

What goes on a formula sheet

A formula sheet that lists formulas alone is half as useful as it could be. For each one, write four things:

One page per chapter. Revise the sheet, not the book, in the last months.

Daily and weekly routine

Once a week, take a timed 45-question physics test across chapters. It trains the switching between topics that the real paper demands.

Speed and time in the exam

NEET gives 180 minutes for 180 questions. Many candidates finish biology faster than one minute a question and give the saved time to physics. A common plan gives physics about 65 minutes, or roughly 85 to 90 seconds a question. See NEET time strategy for a full plan that adds up.

Speed comes from two habits: recognising the question type at once, and eliminating options quickly.

Worked example: eliminating by dimensions. A question asks for the period of a mass m on a spring of constant k, with options (a) 2π√(k/m), (b) 2π√(m/k), (c) 2π√(mk), (d) 2π m/k.

• k has dimensions [M T⁻²], so k/m is [T⁻²], and √(k/m) is [T⁻¹]. Option (a) is a frequency, not a time.
• m/k is [T²], so √(m/k) is [T]. Only (b) has the dimension of time.
• Options (c) and (d) do not reduce to [T] at all. This took about 20 seconds without recalling the formula.

A month-wise plan for the Class 12 year

Dates for the exam and board papers vary each year, so shift the blocks to fit your calendar. A dropper can compress this: about two months per block for Class 11 and Class 12, then mocks from about four months out.

Common traps

• Units: cm with m, μF with F, g with kg. Convert everything to SI before substituting.
• Radians: ω, angular displacement and small-angle approximations need radians.
• Sign conventions in optics and in vertical motion. Fix one and write it down before solving.
• Approximations used outside their range (h ≪ R, small angles).
• Misreading "incorrect", "not" or "which is false". Underline them.

A four-week starter check

• Week 1: finish units, dimensions and errors and kinematics using the five-step loop.
• Week 2: laws of motion and work–energy; start the error book.
• Week 3: one formula page per chapter done so far; first weekly 45-question test.
• Week 4: review the error book; list the three question types that cost you most time and practise 20 of each.
