Quick Answer
The toughest JEE questions are challenging because they demand concept selection, multi-step reasoning, accurate calculation and the ability to avoid attractive wrong approaches. This page contains 60 JEE-style hard practice questions: 20 Mathematics, 20 Physics and 20 Chemistry questions. Every question includes answer options, a worked explanation and a special JEE Trap note so students can understand not only the right answer but also the reason common mistakes happen.
Key Takeaways Before You Start

Hard JEE questions often test two abilities at once. A Mathematics question may appear to be about differentiation but actually depend on the sign of an absolute-value expression. A Physics question may look like a standard wave problem but contain a tension that changes with position. A Chemistry question may appear numerical but depend first on oxidation state or stoichiometry. The table below shows the major hard-question categories students should learn to recognise.
| Subject | Hard Question Type | What It Tests | Student Trap |
|---|---|---|---|
| Mathematics | Functions & calculus | Domains, differentiability, chain rule, maxima/minima | Applying a formula before checking conditions |
| Mathematics | Algebra & complex numbers | Parameters, roots, identities, transformations | Doing a long calculation when a short identity exists |
| Mathematics | Probability & combinatorics | Restricted sample spaces and structured counting | Counting from the wrong sample space |
| Physics | Mechanics & rotation | Constraints, energy, torque and rolling | Using a sliding formula for a rolling system |
| Physics | Electricity & magnetism | Fields, circuits, induction and vector forces | Ignoring geometry, direction or variable quantities |
| Physics | Modern physics & optics | Scaling laws and conceptual equations | Memorising a result without checking what changes |
| Chemistry | Physical Chemistry | Equilibrium, kinetics, electrochemistry and thermodynamics | Unit or stoichiometry errors after a correct formula |
| Chemistry | Inorganic Chemistry | Oxidation states, ligand fields, bonding and trends | Skipping electron configuration or symmetry checks |
| Chemistry | Organic Chemistry | Mechanism, stability, stereochemistry and reaction choice | Choosing a named reaction without checking substrate conditions |

Use the TestPrepKart JEE E-Book to organise syllabus coverage, revision, mock-test planning and engineering admission preparation instead of jumping randomly from one difficult question to another.
Do not use all 60 questions as a speed drill on your first attempt. Solve each question carefully, choose an option and then open the explanation. For every miss, write the real reason: concept, setup, formula, algebra, calculation, unit, interpretation, memory or time pressure. After every 10 questions, review the error log before moving forward. On the second attempt, add time limits.
Use the detailed cards below for learning, then practise additional mixed questions from the JEE Main Paper 1 online test series.
Download JEE Practice QuestionsThese 20 Mathematics questions cover calculus, algebra, probability, matrices, vectors, coordinate geometry and trigonometry. Work for method selection first, then speed.
For x ∈ R, let f(x) = |log 2 − sin x| and g(x) = f(f(x)). Which statement is correct at x = 0?
Near x = 0, log 2 − sin x is positive, so f(x) = log 2 − sin x and f′(0) = −1. Also, log 2 − sin(log 2) is positive. Therefore the outer modulus does not change sign near the relevant point. Using the chain rule, g′(0) = −cos(f(0))·f′(0) = cos(log 2).
A curve y = f(x) passes through (1, −1) and satisfies y(1 + xy) dx = x dy. Find f(−1/2).
Rewrite the equation as dy/dx = y/x + y². Put z = 1/y. Then z′ + z/x = −1. Multiplying by the integrating factor x gives (xz)′ = −x. Hence z = −x/2 + C/x. Using y(1) = −1 gives C = −1/2, so y = −2x/(x² + 1). At x = −1/2, y = 4/5.
A wire of total length 2 units is cut into two parts. One part forms a square of side x and the other forms a circle of radius r. If the sum of the two areas is minimum, which relation is correct?
The length constraint is 4x + 2πr = 2. The total area is A = x² + πr². Differentiate after expressing one variable in terms of the other. The minimum condition gives 2x − 4r = 0, hence x = 2r.
If z = (1 + i)/(1 − i), what is z^2026?
Multiply numerator and denominator by 1 + i. Then z = (1 + i)²/2 = i. Therefore z^2026 = i^2026. Since 2026 ≡ 2 (mod 4), i^2026 = i² = −1.
A is a 2 × 2 nonsingular matrix with det(A) = −2. What is det(2A⁻¹)?
For a 2 × 2 matrix, det(2A⁻¹) = 2² det(A⁻¹) = 4/det(A) = 4/(−2) = −2.
Three fair coins are tossed. Given that at least one head appears, what is the probability of getting exactly two heads?
There are 8 equally likely outcomes for three fair coins. Conditioning on at least one head removes TTT, leaving 7 outcomes. Exactly two heads occurs in HHT, HTH and THH, so the probability is 3/7.
What is the coefficient of x^5 in (1 + x)^8(1 − x)^2?
Since (1 − x)^2 = 1 − 2x + x², the coefficient of x^5 is C(8,5) − 2C(8,4) + C(8,3) = 56 − 140 + 56 = −28.
If Σ from k = 1 to n of 1/[k(k + 1)] equals 9/10, find n.
Use 1/[k(k + 1)] = 1/k − 1/(k + 1). The sum telescopes to 1 − 1/(n + 1) = n/(n + 1). Set n/(n + 1) = 9/10 to get n = 9.
Evaluate ∫ from 0 to 1 of x/(1 + x²) dx.
Let u = 1 + x², so du = 2x dx. The integral becomes (1/2)∫du/u from 1 to 2 = (1/2)ln 2.
Two unit vectors a and b make an angle of 60°. What is |a − b|?
|a − b|² = |a|² + |b|² − 2a·b = 1 + 1 − 2cos60° = 1. Hence |a − b| = 1.
Move from topic-by-topic solving to mixed practice so you learn to identify the correct chapter and method without a heading telling you what the question is testing.
Download JEE Practice QuestionsFind the distance of the point (1, 2, 3) from the plane 2x − y + 2z − 5 = 0.
Distance = |2(1) − 2 + 2(3) − 5|/√(2² + (−1)² + 2²) = |1|/3 = 1/3.
What is the radius of the circle x² + y² − 4x + 6y + 9 = 0?
Complete the squares: (x − 2)² + (y + 3)² = 4. Therefore the centre is (2, −3) and the radius is 2.
The roots of x² − 2x − k = 0 differ by 6. Find k.
For this monic quadratic, the square of the difference of the roots equals the discriminant. The discriminant is 4 + 4k. Since the roots differ by 6, 4 + 4k = 36, giving k = 8.
Evaluate lim as x → 0 of (e^x − 1 − x)/x².
Using e^x = 1 + x + x²/2 + higher-order terms, the numerator becomes x²/2 + higher-order terms. Dividing by x² and taking the limit gives 1/2.
What is the equation of the tangent to y = x^x at x = 1?
Take logs: ln y = x ln x. Then y′/y = ln x + 1. At x = 1, y = 1 and y′ = 1. The tangent is y − 1 = 1(x − 1), or y = x.
A 2 × 2 matrix A has eigenvalues 2 and 3. Find det(A² − I).
The eigenvalues of A² − I are 2² − 1 = 3 and 3² − 1 = 8. The determinant is the product of the eigenvalues, 3 × 8 = 24.
A geometric progression has first term 3 and sum to infinity 12. What is its common ratio?
For |r| < 1, S∞ = a/(1 − r). Thus 12 = 3/(1 − r), so 1 − r = 1/4 and r = 3/4.
How many 5-digit even numbers can be formed using the digits 1, 2, 3, 4, 5 exactly once each?
The last digit must be 2 or 4, giving 2 choices. The remaining four digits can be arranged in 4! = 24 ways. Total = 2 × 24 = 48.
If tan θ + cot θ = 4, what is sin 2θ?
tan θ + cot θ = (sin²θ + cos²θ)/(sinθ cosθ) = 1/(sinθ cosθ) = 4. Hence sinθ cosθ = 1/4 and sin2θ = 2sinθ cosθ = 1/2.
If dy/dx = y tan x and y(0) = 2, what is y(π/3)?
Separate variables: dy/y = tan x dx. Integrating gives ln y = −ln cos x + C, so y = C sec x. Since y(0) = 2, C = 2. Thus y(π/3) = 2 sec(π/3) = 4.

Download JEE Practice QuestionsThese 20 Physics questions cover mechanics, waves, thermodynamics, electricity, magnetism, optics and modern physics. Draw the physical picture before selecting an equation.
The region between two concentric spheres of radii a and b has volume charge density ρ = A/r. A point charge Q is at the centre. What value of A makes the electric field in the region a < r < b constant?
For a Gaussian sphere of radius r, the distributed charge from a to r is 4π∫(A/r′)r′²dr′ = 2πA(r² − a²). Thus E ∝ [Q + 2πA(r² − a²)]/r². For E to be independent of r, the constant term Q − 2πAa² must vanish. Hence A = Q/(2πa²).
A uniform string of length 20 m is suspended vertically. A short wave pulse starts at the lower end and travels upward. Take g = 10 m/s². How long does it take to reach the support?
At height y from the lower end, tension T = μgy. The wave speed is v = √(T/μ) = √(gy). Therefore t = ∫0^20 dy/√(gy) = 2√(20/g) = 2√2 s.
A projectile is launched with speed u at 45° to the horizontal. What is the ratio of its horizontal range R to its maximum height H?
At 45°, R = u²/g. Maximum height H = u²sin²45°/(2g) = u²/(4g). Hence R/H = 4.
A solid cylinder rolls without slipping down an incline of angle θ. What is the acceleration of its centre of mass?
For rolling, a = gsinθ/[1 + I/(mR²)]. For a solid cylinder I = (1/2)mR². Therefore a = gsinθ/(1 + 1/2) = (2/3)gsinθ.
A particle in SHM has amplitude A. When its displacement is A/2, what fraction of the total energy is kinetic?
Total energy is (1/2)kA². Potential energy at x = A/2 is (1/2)k(A²/4), which is one-fourth of the total. Therefore the kinetic-energy fraction is 1 − 1/4 = 3/4.
The escape speed from the surface of a planet is v₀. What is the escape speed from a point at a height equal to the planet’s radius above the surface?
Escape speed is √(2GM/r). At the surface r = R. At height R, r = 2R. Therefore the speed becomes v₀/√2.
One mole of a monatomic ideal gas expands at constant pressure from volume V to 2V. If the initial temperature is T, what is Q/W for the process?
At constant pressure, doubling volume doubles temperature, so ΔT = T. Work W = nRΔT = RT. For a monatomic gas, ΔU = (3/2)RT. Hence Q = ΔU + W = (5/2)RT, so Q/W = 5/2.
Three identical capacitors of capacitance C form the three sides of a triangle. What is the equivalent capacitance between any two vertices?
Between the chosen vertices, one capacitor C is directly connected. The other two capacitors form a series path with equivalent C/2. These two branches are in parallel, giving C + C/2 = 3C/2.
A cell of emf E and internal resistance r is connected to a variable load resistance R. For maximum power delivered to the load, what should R be?
The load power is P = E²R/(R + r)². Differentiating with respect to R, or using the maximum-power-transfer theorem, gives R = r.
A charged particle enters a uniform magnetic field perpendicular to the field. Which expression gives its time period of circular motion?
The magnetic force provides centripetal force: qvB = mv²/r, so r = mv/(qB). The period is 2πr/v = 2πm/(qB), independent of speed.
Move from topic-by-topic solving to mixed practice so you learn to identify the correct chapter and method without a heading telling you what the question is testing.
Download JEE Practice QuestionsIn crossed electric and magnetic fields, a charged particle passes undeflected. If E and B are perpendicular to each other and to the velocity, what is the particle speed?
For no deflection, electric and magnetic forces balance: qE = qvB. Therefore v = E/B.
A coil has N turns and area A. A uniform magnetic field perpendicular to the coil changes from 0 to B in time Δt. What is the magnitude of the average induced emf?
The change in flux per turn is BA. Flux linkage changes by NBA. Faraday’s law gives average emf = NBA/Δt.
In a series LCR circuit at resonance, what is the magnitude of the impedance?
At resonance XL = XC, so the net reactance is zero. The impedance becomes Z = √[R² + (XL − XC)²] = R.
A thin converging lens has power +2 dioptres. What is its focal length?
Power P = 1/f when f is in metres. Thus f = 1/2 = 0.5 m.
In a Young’s double-slit experiment, a glass plate of refractive index 1.5 and thickness 2λ is placed in front of one slit. By how many fringes does the pattern shift?
The additional optical path is (μ − 1)t = 0.5 × 2λ = λ. A path change of one wavelength shifts the pattern by one fringe.
For a metal, the incident frequency is initially 2ν₀, where ν₀ is the threshold frequency. The frequency is then doubled. What is the ratio of the new stopping potential to the original stopping potential?
Initially eV₁ = h(2ν₀ − ν₀) = hν₀. After doubling, the frequency is 4ν₀, so eV₂ = h(4ν₀ − ν₀) = 3hν₀. Therefore V₂/V₁ = 3.
For a hydrogen atom, what is the ratio of the radius of the n = 3 orbit to the radius of the ground-state orbit?
For hydrogen, rn ∝ n². Hence r3/r1 = 3²/1² = 9.
An electron is accelerated through a potential difference V and has de Broglie wavelength λ. What is its wavelength when accelerated through 4V?
For a non-relativistic electron accelerated through V, momentum p ∝ √V, so λ = h/p ∝ 1/√V. Increasing V by a factor of 4 halves the wavelength.
What are the dimensions of Planck’s constant h?
From E = hν, h = E/ν. Energy has dimensions ML²T⁻² and frequency has T⁻¹, so h has ML²T⁻¹.
Using a simple pendulum, g is calculated from g = 4π²L/T². If the maximum percentage errors in L and T are 1% and 2% respectively, what is the maximum percentage error in g?
For products and powers, maximum fractional errors add with the absolute values of the powers. Thus Δg/g = ΔL/L + 2ΔT/T = 1% + 4% = 5%.

Download JEE Practice QuestionsThese 20 Chemistry questions cover Physical, Inorganic and Organic Chemistry. Before calculating, identify oxidation state, reaction type, equilibrium relation or structural condition.
Which pair has the same spin-only magnetic moment? Atomic numbers: Cr = 24, Mn = 25, Fe = 26, Co = 27.
Cr²⁺ is d⁴ and Fe²⁺ is d⁶. With H₂O as a weak-field ligand, both are high spin and each has four unpaired electrons. Therefore their spin-only magnetic moments are equal.
Which complex shows optical isomerism? Here en = ethylenediamine.
The cis complex containing two bidentate en ligands can form non-superimposable mirror images. The corresponding trans form has symmetry that prevents optical activity.
The decomposition of H₂O₂ is first order. Its concentration falls from 0.5 M to 0.125 M in 50 min. What is the rate of O₂ formation when [H₂O₂] = 0.05 M?
A fall from 0.5 M to 0.125 M is two half-lives, so t1/2 = 25 min and k = ln2/25 = 0.02772 min⁻¹. The disappearance rate of H₂O₂ at 0.05 M is k[H₂O₂] = 1.386 × 10⁻³ M min⁻¹. From 2H₂O₂ → O₂ + 2H₂O, the O₂ formation rate is half of this, 6.93 × 10⁻⁴ M min⁻¹.
What is the ionization energy of a hydrogen atom in the n = 2 state?
The energy of the nth level in hydrogen is −13.6/n² eV. At n = 2, E = −3.4 eV. Therefore 3.4 eV is required to ionize the atom from that level.
What is the bond order of O₂⁺ according to molecular orbital theory?
O₂ has bond order 2. Removing one electron from an antibonding π* orbital increases the bond order by 1/2, giving 2.5 for O₂⁺.
For a reaction, ΔH = −40 kJ mol⁻¹ and ΔS = −100 J mol⁻¹ K⁻¹. In which temperature range is the reaction spontaneous under standard conditions?
Convert ΔS to −0.100 kJ mol⁻¹ K⁻¹. Then ΔG = ΔH − TΔS = −40 + 0.100T. Spontaneity requires ΔG < 0, which gives T < 400 K.
For N₂O₄(g) ⇌ 2NO₂(g), how are Kp and Kc related?
Kp = Kc(RT)^Δn. Here Δn = 2 − 1 = 1, so Kp = Kc(RT).
A 0.01 M weak monoprotic acid has Ka = 1 × 10⁻⁴. What is its approximate pH?
For a weak acid, [H⁺] ≈ √(KaC) = √(10⁻⁴ × 10⁻²) = 10⁻³ M. Thus pH ≈ 3. The more exact value is only slightly above 3.
A buffer contains equal concentrations of a weak acid HA and its salt NaA. What is the pH of the buffer?
Henderson-Hasselbalch gives pH = pKa + log([A⁻]/[HA]). Equal concentrations make the ratio 1, so log1 = 0 and pH = pKa.
For an electrochemical cell with E°cell = 1.10 V and n = 2, what is ΔG°? Take F = 96500 C mol⁻¹.
ΔG° = −nFE° = −2 × 96500 × 1.10 J mol⁻¹ = −212300 J mol⁻¹ = −212.3 kJ mol⁻¹.
Move from topic-by-topic solving to mixed practice so you learn to identify the correct chapter and method without a heading telling you what the question is testing.
Download JEE Practice QuestionsA solution contains 1 mol of a non-volatile solute and 9 mol of solvent. What is the mole fraction of the solute?
Total moles = 1 + 9 = 10. Mole fraction of solute = 1/10 = 0.10.
Assuming complete dissociation, what is the van’t Hoff factor i for CaCl₂ in dilute aqueous solution?
One formula unit of CaCl₂ gives one Ca²⁺ ion and two Cl⁻ ions, a total of three particles. For ideal complete dissociation, i = 3.
How many unpaired electrons are present in [Fe(CN)₆]⁴⁻?
In [Fe(CN)₆]⁴⁻, Fe is +2 and therefore d⁶. CN⁻ is a strong-field ligand, giving a low-spin octahedral arrangement t2g⁶eg⁰ with no unpaired electrons.
What is the oxidation state of Mn in KMnO₄?
Let Mn be x. K is +1 and four oxygens contribute −8. Charge balance gives 1 + x − 8 = 0, so x = +7.
Which is the stronger Lewis base under comparable conditions: NH₃ or PH₃?
The lone pair on nitrogen is more available for donation than the lone pair on phosphorus in PH₃. Therefore NH₃ is the stronger base in the usual comparison.
Which order of acidity is correct?
The nitro group withdraws electron density and stabilizes the phenoxide ion, increasing acidity. The methyl group donates electron density and destabilizes the phenoxide ion, reducing acidity relative to phenol.
How many stereoisomers does 2,3-dichlorobutane have?
There are two enantiomers, (2R,3R) and (2S,3S), plus one meso form (2R,3S), giving three stereoisomers in total.
Reductive ozonolysis of propene produces which pair of carbonyl compounds?
Propene is CH₃−CH=CH₂. Cleavage of the double bond gives CH₃CHO from the substituted carbon and HCHO from the terminal CH₂ carbon.
Which substrate generally undergoes SN1 solvolysis fastest under the same conditions?
SN1 rate is controlled mainly by carbocation formation. A tertiary carbocation is much more stable than secondary or primary carbocations, so tert-butyl chloride reacts fastest.
Which compound undergoes the Cannizzaro reaction readily in concentrated base?
The Cannizzaro reaction is characteristic of aldehydes that do not have an α-hydrogen. Benzaldehyde has no α-hydrogen, while acetaldehyde and propanal do. Acetone is a ketone.

Download JEE Practice QuestionsStudents often lose difficult questions for repeatable reasons. Instead of writing only “careless mistake,” identify the exact failure pattern. The table below can be used as an error-log guide.
| Mistake | What It Looks Like | Correction |
|---|---|---|
| Concept selection | You know formulas but choose the wrong chapter idea. | Write the concept name before the first equation. |
| Hidden condition | You ignore modulus sign, domain, symmetry, rolling or strong-field/weak-field information. | Underline restrictive words before solving. |
| Long method | You solve for more information than the question asks. | Check whether an identity, ratio or option elimination is enough. |
| Sign or unit error | Method is correct but final value is wrong. | Run a 10-second sign and dimension check. |
| Chemistry condition error | You recall a reaction but ignore substrate, α-H, ligand strength or oxidation state. | Write the reaction condition before predicting the product or property. |
| Time-pressure error | You continue a difficult problem for too long. | Set a decision point: continue, mark for review or move on. |
This plan follows the same idea as the long SAT reference: first solve without rushing, then retake mistakes, then move to timed mixed sets. Adapt the daily volume to your current preparation level.
| Days | Focus | What To Do |
|---|---|---|
| Days 1–3 | Hard Mathematics foundations | Complete Q1–Q10 without strict timing. Tag every miss as concept, algebra, identity, calculation or method selection. |
| Days 4–6 | Hard Mathematics mixed practice | Complete Q11–Q20. Retake all missed Mathematics questions without opening the explanation first. |
| Days 7–9 | Hard Physics mechanics & electricity | Complete Q21–Q30. For every miss, redraw the diagram and write the governing principle. |
| Days 10–12 | Hard Physics waves, optics & modern physics | Complete Q31–Q40 and retake missed questions with a short time limit. |
| Days 13–15 | Hard Physical & Inorganic Chemistry | Complete Q41–Q53. Label misses as calculation, equilibrium, oxidation state, ligand field, factual recall or unit error. |
| Days 16–17 | Hard Organic Chemistry | Complete Q54–Q60 and build a reaction-condition error list. |
| Days 18–19 | Timed mixed PCM sets | Mix questions from all three subjects. Track accuracy, time per question and decision-making. |
| Days 20–21 | Final error-log review | Retake only the questions you previously missed. Before solving, explain the trap you expect to avoid. |
These are illustrative preparation scenarios, not claims about named students or guaranteed score outcomes. They show how different error patterns can be corrected using the question set.
A student understands calculus and algebra but loses marks through sign errors and overlong methods. The better plan is to solve Q1–Q20 untimed, tag each error and then retake only the missed questions with a method-selection rule: write the shortest possible route before calculation.
A student can explain formulas but spends too long on variable-tension, rolling and field questions. The correction is to practise Q21–Q40 with a decision point: after the setup, decide whether the problem needs energy, force, Gauss’s law, Faraday’s law or a scaling relation before continuing.
A student studying outside India may be strong in school coursework but less familiar with JEE-style coordination chemistry, multi-step Mathematics or rapid numerical Physics. The efficient route is syllabus-gap analysis first, then PYQs, then Q1–Q60 and finally mixed online tests.
NRI and international students may study through American, IB, British, CBSE or other curricula. Their school subjects can overlap strongly with JEE, but the sequence, depth and style of competitive problem solving may differ. Instead of repeating country keywords throughout the page, use one dedicated strategy section like this.
Students preparing from the USA, UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain and other countries can use hard-question practice to become comfortable with Indian competitive-exam-style calculations, option analysis and mixed Physics-Chemistry-Mathematics problem solving.
After completing the 60 worked question cards, continue with TestPrepKart’s JEE Main Paper 1 online test series for additional question practice.
Download JEE Practice QuestionsTestPrepKart supports structured JEE preparation with topic practice, mock-test planning, doubt support and personal guidance for students in India and abroad.
They are most useful after the student has basic chapter concepts in place. Beginners can still use them, but should study the underlying concept and standard examples before worrying about speed.
Start with a manageable set such as 6–10 difficult questions and spend enough time reviewing errors. The quality of analysis matters more than the raw number solved.
Usually, complete standard chapter practice and previous-year questions first. Then use difficult questions to add depth, method flexibility and error control.
This page is designed as JEE-style hard practice. It should not be treated as an official past-paper archive. Use the TestPrepKart download area and official exam resources separately for past-paper practice.
Start with the subject where your concepts are strongest so you learn the error-review process quickly. Then apply the same process to the weaker subjects.
Typical difficulty comes from hidden conditions, parameter relationships, multiple possible methods, transformations, long algebra or the need to combine two chapters.
Physics becomes difficult when the physical situation is not standard, a quantity changes with position or time, several laws could apply or the direction and sign choices are easy to mishandle.
Chemistry questions often become difficult when a calculation depends on correct stoichiometry, a coordination question depends on ligand field strength, or an organic reaction depends on a structural condition.
No. Tough questions improve depth, while mock tests train timing, question selection, endurance and subject switching. Both have different roles.
Before your second attempt, cover the answer and read only the trap label. Try to explain the mistake you must avoid, then solve the question again.
Yes. NRI and international students can use it after checking syllabus gaps. It is particularly useful for adapting to JEE-style option analysis, calculation speed and mixed-concept problems.
Use the TestPrepKart JEE Main Paper 1 online test series link provided several times on this page for additional practice questions and tests.
Final JEE Practice Rule
Do not measure progress only by how many hard questions you complete. Measure whether the same mistake disappears on the next attempt. A strong cycle is Concepts → Standard Questions → PYQs → Tough Questions → Mock Tests → Error Analysis → Revision.
