what are the important topics in physics, chemistry and mathematics that need to be thoroughed for Jee main examination?

Hello,


JEE Main Important Topics for Physics

Magnetics-One of the topic from which maximum questions are asked in the question paper.
Optics-It is a relatively easy topic to study.
Modern Physics-It is one of the important and scoring topics for both JEE Main and JEE Advanced. Also, candidates must check sub-topics such as radioactive decay of substances, nuclear fission and fusion, dual nature of matter and X-rays in detail.
Electromagnetic Induction and AC-  Generally, numerical problems are asked from this topic.
Oscillation and Waves-Must study this topic in detail.
Electrostatics- According to the previous year trend, this is the most scoring topic as almost four questions are asked from it every year in.
Current Electricity- Another important topic which candidates need to cover. Ohms law, colour code for resistors etc are asked from this.
JEE Main Important Topics for Chemistry

Organic Chemistry- Purification and Characterisation of Organic Compounds, Some Basic Principles of Organic Chemistry, Hydrocarbons, Organic Compounds Containing Oxygen, Organic Compounds Containing Nitrogen, BioMolecules etc.
Physical Chemistry- Some Basic concepts in Chemistry, Atomic Structure, States of Matter, Chemical Bonding and Molecular Structure, Surface Chemistry, Chemical Thermodynamics, Equilibrium, Chemical Kinetics, and Redox Reactions and Electrochemistry.
Inorganic Chemistry- Classification of Elements and Periodicity in Properties, General Principles and Process of Isolation of Metals, Hydrogen, s - Block Elements (Alkali and Alkaline Earth Metals), Co-ordination Compounds, Environmental Chemistry to name few.
JEE Main Important Topics for Mathematics

Permutations & Combinations
Definite Integration
Quadratic Equation
Conic Section

Application of Derivatives
Vector & 3D Geometry
Complex Numbers
Coordinate Geometry; Matrices in Algebra: Circle, Parabola, Hyperbola in Coordinate Geometry

I hope this helps.

Hello,

There is no such thing as it may get change this year. There are certain topics where question comes in higher frequency but it changes every year. For a generic purpose read all the topics with equal important and depth. This will help you get a broader view and you will be able to attend the paper with 100% confidence.

Now you have time to go through the concepts and solve the numericals. It's not easy as every chapter has innumerous questions but try to cover concepts mostly in a week and repeat it in every week. Solve as many questions you can. If you want to secure a good position you have to give most of your time. You have to give 18 hours daily so that you can cover atleast 3 chapters from each subject. So that you can cover the whole 3 subject in a week.

This is hard but you have to do it. a candidate you score a rank below  2-3K gets a chance to take admission in NIT and to appear JEE advance. for a rank range upto 10K there will be many candidates and competition is higher. Prepare accordingly.

Hope it helps!
