must to be done chapters for jee mains in last 1 week

To begin with, it should be clear that the NTA body review does not give any weighting to any of the chapters. All chapters are critical for NTA.

If you are preparing for JEE Mains 2020 or 2021, we will recommend that you go through the JEE Main syllabus and plan all subjects.

But of course, if you're preparing for JEE Mains 2020 and are in your final lap of preparation, then this is relevant.

According to last year's question paper, these were topics with highest weightage.

• Electrodynamics
• Mechanics
• Modern Physics
• Heat and Thermodynamics
• SHM & Waves
• Optics
• Differential Calculus
• Integral Calculus
• Coordinate Geometry
• Matrix & Determinants
• Coordinate Geometry (3-D)
• Probability
• Matrix and Determinants
• Trigonometry
• Organic Chemistry-II [Alkyl Hallide, Alcohol & Ether (Reaction Mechanism), Aromatic Compounds, Biomolecules, Carbohydrates, Amino Acids and Polymers, Carbonyl Compounds, Environmental chemistry, Grignard Reagent, Reduction, Oxidation & Hydrolysis]
• Physical Chemistry-I [Atomic Structure & Nuclear Chemistry, Ionic Equilibrium, Mole Concept, Thermodynamics and Thermochemistry]
• Physical Chemistry-II [Chemical Kinetics, Electrochemistry, Solid State, Solution & Colligative Properties, Surface Chemistry]
• Inorganic Chemistry-I [Chemical Bonding, Periodic Table & Periodicity in Properties, S-Block]

Applicants may refer to these topics during the last minute of planning, but should not devote their entire time to them alone.

Here are topics which are important.

Hello Nikita,

It depends on your preparation level. I suggest you to not to do any new topics in last week, instead lay more stress on revising and solving more and more question papers.

However, there are some topis that you may consider to be done if you don;t have good preparation. Preparing these will assure atleast passing marks. The topics include:

Mathematics-

• Heights and Distances
• Area under the curve
• Coordinate Geometry
• Integration
• Vector algebra and Vectors
• Mathematical Reasoning
• Statistics

Physics

• Optics
• Work, Energy, Power
• Modern Physics
• Units, Dimensions, and Vectors

Chemistry-

• Chemical Bonding
• Inorganic Chemistry
• Periodic Table
• Mole Concept
• Atomic Structure
