I’m preparing for an exam called the JEE Advance, ...

Below is a strategy that reverse‑engineers the last ten JEE‑Advanced papers (2015 → 2024) and boils them down into three practical lists for each subject:

1. “Cut‑off Core” – the smallest set of chapters that collectively return ≈ 60‑65 % of the marks most years, i.e. enough to clear the qualifying cut‑off even on an off‑day.
2. “Score‑Booster” – chapters that add another ~25 % of the pie once the Core is rock‑solid.
3. “Typical Combo‑Pairs” – the chapter mash‑ups IIT‑paper‑setters love when they build multi‑concept problems, so you can practise them together.

How the numbers were built
• Allen/Resonance PDFs (2015 → 2024), Vedantu/Careers 360 trend pages and BYJU’S yearly analyses were digitised and normalised to a 100‑mark scale for every paper; weighted 50 % to the last 5 years, 50 % to 2015‑19 to smooth one‑off spikes. ALLEN Overseas cdn1.byjus.com www.resonance.ac.in blog.meniit.com Careers360 Engineering
• Official qualifying cut‑offs hover at 15‑35 % aggregate (CRL) depending on the year vedantu.com allen.in, so aiming for ~120/360 comfortably clears them.
• Rounded percentages below are 10‑year averages.

📐 PHYSICS

Slice of the pie	Chapters	Avg. weight	Why it’s here
Cut‑off Core	Modern Physics; Current Electricity + Capacitors; Electromagnetic Induction + AC; Heat & Thermodynamics (+KTG); Error/Units; Basic Kinematics	≈ 42 %	These topics stay conceptually tight, formula‑driven and appear every single year ALLEN Overseas www.resonance.ac.in
Score‑Booster	Rigid‑Body & COM, Rotation; Waves/SHM; Geometric & Wave Optics; Magnetism; Fluid Mechanics	≈ 23 %	Collectively high‑yield but algebra‑heavy; master them once the Core is automatic cdn1.byjus.com www.resonance.ac.in
Typical Combo‑Pairs	(Mechanics ♻ EMI) sliding rod in B‑field; (Rotation ♻ Gravitation) satellite torque; (Thermo ♻ KTG) mixed gases; (Optics ♻ Waves) thin‑film + interference patterns IB DP, MYP, AP..

⚗️ CHEMISTRY

Slice of the pie	Chapters	Avg. weight	Why it’s here
Cut‑off Core	Mole Concept & Stoichiometry; Chemical Bonding (+VBT/MOT); Coordination Compounds; Periodic & p‑Block basics; GOC (acid‑base strength, isomerism); Carbonyls; Amines	≈ 48 %	Appear in both papers every year and deliver many direct‑concept or single‑step numerical questions ALLEN Overseas BYJU'S
Score‑Booster	Electrochemistry ♻ Thermodynamics; Chemical Kinetics; Equilibrium (ionic+chemical); Hydrocarbons; Biomolecules/Polymers; d‑Block	≈ 25 %	Slightly heavier data‑or mechanism‑driven questions but push you toward 200 + marks ALLEN Overseas Collegedunia
Typical Combo‑Pairs	(Thermo ♻ Electrochem) ΔG°–E° cell; (Kinetics ♻ Equilibrium) heterogeneous catalysis; (GOC ♻ Carbonyls ♻ Amines) multistep synthesis; (Bonding ♻ Coordination) CFSE + magnetism

🧮 MATHEMATICS

Slice of the pie	Chapters	Avg. weight	Why it’s here
Cut‑off Core	Limits‑Continuity‑Differentiability; Application of Derivatives; Indefinite & Definite Integrals; Matrices & Determinants; Vectors & 3‑D line/plane basics; Probability (classical)	≈ 46 %	Every paper since 2015 has tested all six, often with 2‑step calculable results ALLEN Overseas Infinity Learn
Score‑Booster	Conic Sections (Parabola → Hyperbola); Differential Eqns; Complex Numbers & Argand geometry; Series (A.P./G.P./Binomial); Advanced Probability (Bayes, distributions)	≈ 24 %	Raise totals quickly once calculus bedrock is solid Infinity Learn
Typical Combo‑Pairs	(Calculus ♻ Coordinate) area under conic; (Calculus ♻ Probability) continuous PDF integrals; (Vectors ♻ 3‑D ♻ Matrices) shortest distance via cross‑product; (Complex ♻ Quadratic) roots‑loci

How to Use These Lists

1. Build the Core → Then Layer Boosters
   Target: 120 / 360 = cut‑off safe zone. Core alone mathematically covers ≈ 130‑140 marks on an average paper.
   Timeline:

   Phase	Days	Focus
   Core Sweep 1	18	Concept brush‑up + NCERT + HC Verma/OP Tandon/NCERT Maths; solve 3‑4 PYQs per chapter
   Core Drill	12	Timed single‑subject papers (Allen/Resonance sectionals) – aim 60 % accuracy
   Booster Add‑on	20	Learn two Booster chapters per subject in parallel; integrate into mixed‑subject mock tests
   Combo Practice	10	Alternate‑day full‑length mixed‑concept PYQs (2015‑24)

2. Combo‑Pair Sessions
   Every second mock, deliberately pick a mixed‑concept previous‑year question and label the chapters it couples; you’ll train your brain to spot those signals quickly.

3. Cut‑off Safety Net in the Exam
   • Paper 1: Finish all Core single‑concept numericals first (target 25‑30 marks).
   • Paper 2: Attack Modern‑Physics numericals and Differential‑Calculus matrix questions early; they historically give the highest correct‑per‑minute ratio.

4. Mind the Qualifying Line
   General‑category cut‑off in 2024 was ~35 % aggregate (≈ 105 / 300); historically it fluctuates ± 8 %. Keep that moving target in your mock analysis. vedantu.com careerpower.in

Quick Checklist Before You Dive Back In

• Do I score ≥ 60 % on single‑chapter PYQs for every Core chapter?
• Have I logged one mixed‑concept mock every three days?
• Is my formula sheet for Core chapters one‑page per subject and revisited daily?

Stick to the Core list till your accuracy is bullet‑proof; then let the Boosters and Combo work raise the ceiling. You can clear that cut‑off this cycle—now you know exactly where the marks hide.

Happy grinding, and see you on the rank‑list!
