As asked by you list of important and scoring topics or chapters is given below subject wise along with their chapter wise weight age based on past year papers :-

PHYSICS

*Modern Physics:- 20 marks
*Heat and Thermodynamics :- 12 marks
*Optics:- 12 marks
*Current Electricity :- 12 marks
*Electrostatics :- 12 marks
*Magnetics :- 8 marks

CHEMISTRY

*    Transition Elements and Coordination Chemistry  :-  12 marks
* Periodic table and Representative Elements :- 12 marks
* Thermodynamics And Gaseous State:- 8 marks
* Atomic Structure:- 8 marks
* Chemical Bonding:- 8 marks
* Chemical And Ionic Equilibrium:- 8 marks

MATHS

* Coordinate Geometry  :-  20 marks
* Limits, Continuity and Differentiability :- 12 marks
* Integral Calculus :- 12 marks
* Complex numbers and Quadratic Equation :- 8 marks
* Matrices and Determinants :- 8 marks
* Statistics and Probability :- 8 marks
* Vector Algebra :- 8 marks

To help you plan your studies ,you can get the chapter wise weightage of all the chapters at

https://engineering.careers360.com/articles/jee-main-syllabus-weightage

Also, follow the below tips :-

*Make routine or timetable :- you can make a routine as well and try to give at least 8 hours or more to study , your routine should revolve around things i.e study, revise and practice

•PHYSICS is the  toughest part for most of the aspirants  as it has both numericals and concepts to deal with , so keep at least 3 hours each day for Physics.

•In Chemistry you have to deal with reactions and learn them and solve questions as well, so give at least 2 hours daily to Chemistry

•Mathematics is all about practising questions, so try to give at least around 3 hours each day for maths

* Plan your studies, and set daily, weekly and monthly goals to cover the syllabus and meet them without any fail.

*After completing each chapter , you should go through mcqs and numericals of the same chapter

*Make short notes of important formulas and concepts for each chapter and Keep revising it

*Solve previous year JEE MAINS questions , it will let you know the examination pattern, type question etc so that you can prepare accordingly

*Go through JEE MAINS mock test papers , it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination

Dear aspirant,

According to your query you want me to suggest you some important chapters in each subject and so i would suggest you the chapters looking the time left for jee mains-

At first I would recommend you to buy the arihant 40 days jee mains book of physics, chemistry and maths as that would be very helpful for the end days as you would get the knack of the kind of questions that would be asked in jee mains 2021.

For physics- Semiconductor, communication systems,current electricity, fluid mechanics,mechanics of solids, wave optics.

For maths- Statistics,vectors and 3-D, probability and PNC , binomial, diffrential equation,interal calculus

For chemistry-Solutions,chemical kinetics,thermodynamics,polymers,biomolecules,chemical bonding, chemistry in everyday life , environmental chemistry.
