Summary of “JEE Mains 2026: Don’t Skip These Chapters if you want 99%ile | High Weightage | eSaral”

Focus on 30 High-Weightage Chapters: Over the last 5 years, about 70% of JEE Mains marks come from just 30% of the syllabus chapters (around 30 chapters). Prioritizing these chapters can almost guarantee a 99 percentile score.
Strategic Preparation Over Covering Everything: Completing all 80+ chapters is unrealistic in limited time. Instead, thorough preparation of these 30 chapters, focusing on important subtopics within them, is the key to success.
Target Scores for 99 Percentile:
- Physics: ~75 marks
- Chemistry: ~70 marks
- Mathematics: ~50 marks
- Overall: Between 170-185 marks (can vary with difficulty and shifts)
Four Categories of Chapters:
1. Easy and frequently asked
2. Tough but frequently asked
3. Easy but rarely asked
4. Tough and rarely asked Focus only on categories 1 and 2, as they yield the highest returns.

Coordination Compounds: Focus mainly on Crystal Field Theory (CFT) and Crystal Field Stabilization Energy (CFSE), which cover 70% of questions here.
Mole Concept and Stoichiometry: Concentration terms like molarity are heavily tested.
Hydrocarbons: Focus on aromatic hydrocarbons and their reactions (practical organic chemistry).
Chemical Bonding: Only three subtopics are crucial:
- Hybridisation
- VSEPR (Valence Shell Electron Pair Repulsion) theory
- Molecular Orbital Theory (MOT) These cover 80% of the questions in this chapter.
D & F Block Elements: Focus on exceptional configurations (e.g., Europium, Gadolinium) through PYQ patterns rather than rote memorization.
General Organic Chemistry (GOC): Key areas: acidic/basic strength and aromaticity.
Liquid Solutions: Abnormal colligative properties and van’t Hoff factor are important.
Chemical Kinetics: Focus on first-order reactions and Arrhenius equation.
Periodic Table: Emphasize ionization energy comparisons, atomic radius, and isoelectronic species.
Biomolecules: NCERT-based preparation is crucial.
Carboxylic Acids and Derivatives: Small but consistently asked.
Atomic Structure: Focus on Bohr model (energy, radius, velocity) and quantum numbers (cover 80% of questions).
P Block Elements: Questions can come from anywhere; though longer, solving is quick.

Ray Optics: Frequently asked, sometimes multiple questions per shift.
Modern Physics: Highest average weightage among topics.
Electrostatics and Gravitation: Electrostatics is heavily tested; gravitation concepts overlap and are easier once electrostatics is understood.
Thermodynamics: Relatively easy, consistently asked.
Fluid Mechanics: Focus on viscosity and surface tension (over 50% of questions).
Rotation: Moment of inertia and angular momentum (over 50% of questions).
Magnetic Effects of Current, Unit Dimensions, Current Electricity: Important and consistently tested.
Semiconductors and Electromagnetic Waves: Small chapters but should not be ignored.
Unit Dimensions: Increasing weightage over recent years; easy but important.

3D Geometry and Vectors: Most frequently asked, though calculative and lengthy.
Sequences and Series: Easy and short, consistently asked with high average marks.
Definite Integration: Longer and tougher but important.
Probability and Permutations & Combinations (PNC): PNC first, then probability builds on it.
Binomial Theorem: Small chapter with high weightage.
Straight Lines: Small but frequently asked.
Area Under the Curve, Differential Equations, Functions, Matrices and Determinants: High weightage chapters.

Prioritize Selected PYQs (Previous Year Questions):
- Total PYQs available: 7,000-8,000 (too many to do all)
- Focus on a curated set of 2,000-2,500 PYQs, divided into two parts for JEE Main 1 and 2 preparation.
- These sets are designed to avoid repetition and maximize scoring potential.
Daily Study Plan:
- Study theory: 6 hours/day (finish syllabus by end of December)
- Revision: 2 hours/day (ongoing)
- Practice + Tests: 6 hours/day (includes solving PYQs and mock tests)
Test Frequency:
- Minimum 2 tests per week starting November (more tests improve scores and confidence)
- Utilize test analysis reports (like the Brahmastra AI-powered test series) for detailed feedback on strengths and weaknesses.
Smart Preparation:
- Focus on high-yield topics and subtopics
- Practice selectively and consistently
- Regular revision and testing to build confidence and improve percentile gradually

Even students with low preparation by November (30-40%) have scored 99+ percentile by focusing smartly on these chapters in the last 2-2.5 months.

Consistency and smart work are more important than trying to cover everything superficially.
Anxiety and panic are common but following a structured plan will help improve scores steadily.

Main Speaker: Unnamed male instructor from eSaral, experienced JEE mentor with 10+ years of teaching and coaching experience.
Mentioned Students:
- Shivangi (99.7 percentile)
- Isham (jumped from 34 percentile to 99.79 between JEE Main 1 and 2) Both cited as examples of success through smart preparation.
