Is communication an important chapter for jee main .

Physics:

These 3 are the most basic concepts that you ought to know. You can expect at-least 1 question from these topics:

Units and Dimensions – Weightage: 2%

Measurement of Errors – Weightage: 2%

Vectors

These topics are classified as fundamentals in physics. You can expect 1 – 2 questions from this section on an actual JEE Paper.

Kinematics – Weightage: 1%

Newton’s Laws of Motion – Weightage: 4%

Friction

These 5 topics are important & easy and can help your score high marks very easily in the JEE:

Work, Energy and Power – Weightage: 5%

Electrostatics – Weightage: 6%

Current Electricity – Weightage: 7%

Wave Optics – Weightage: 5%

Ray Optics – Weightage: 6%

These 9 topics are absolutely important for JEE. You can expect twisted questions from these sections, so its very important you know your basics well and you practice alot. You can expect 2 – 3 questions from most of the topics listed below.

Centre of Mass, Momentum and Collision – Weightage: 5%

Rotational Dynamics – Weightage: 4%

Simple Harmonic Motion – Weightage: 5%

Fluid Mechanics – Weightage: 2 – 5%. Bernoulli’s principle can be easily twisted to ask some tricky questions.

Wave Motion and String Waves – Weightage: 5%

Magnetism – Weightage: 6%

Heat & Thermodynamics – Weightage: 6%. This is one topic that is very important for both Physics and Chemistry preparation in JEE.

Nuclear Physics – Weightage: 5%

Modern Physics – Weightage: 5%

And finally, here is a list of the topics that you should study atleast once and try to create cheat-sheets or flashcards to help your revise the formulas. You can expect 3 – 4 questions mix and match from the topics below.

Circular Motion – Weightage: 1%

Gravitation – Weightage: 1%

Properties of Matter, Elasticity – Weightage: 2%

Sound Waves

Electromagnetic Induction – Weightage: 3%

Alternating Current – Weightage: 1%

Heat Transfer

Calorimetry

Thermal Expansion

Thermo Electricity

Semiconductors and Electronic Devices – Weightage: 5%

Communication Systems – Weightage: 2%

Hello,

No communication does not hold any importance in JEE Mains all you need is to have a good command on Physics Chemistry and Mathematics.

All the Best
