Hello

This are some of the following  chapters which you have to prepare to score 180 maeks in jee mains :

Physics:basic  circular motion, work power energy, recitilinear motion , modern physics,  nuclear physics , electrostatic..

Maths:fundamental of mathematics,  vector , calcus part , coordinate geometry..

Chemistry: moles , gases and solid states , solution , coordinate compound , chemical eqilibrium,  p - block , chemical bounding,  thermodynamic..

Go through this topic very deeply  understand the concept and basic .

Go through  previous years paper and solve as much question as possible.. give mock test at last..

Feel free to ask

Good Luck...

hello,

Iam not an engineering student though i would like to give you some tips that would help you in terms of syllabus,

Physics -

Rectilinear motion is something very basic and not to be missed thing .

Basic circular motion and detailed work power energy ….(this was the key weapon of JEE advanced 2018 .30%of the whole paper,might be featured in mains too. (20 marks )

Modern physics and nuclear physics.(most important and scoring part,this can give you 20+ marks alone )

Basic Electrostatics(dipole , line charge ,gauss law ,dont study conductor ,it will ruin whole chapter)… force part of Electromagnetism ,rotational emf just basic. 20+ marks

So you are now prepared for at least 50–60 marks ,try to select questions and solve them with full dedication(perfection needed) 40+would be a decent score .

If you avoid problem solving,you wont be able to make even 20 marks ,so better thing is practice like a pro.(you can easily maximize it upto 50 )

Maths

Fundamentals of mathematics (integral component of maths ,cant be missed)Coordinate geomtry and Calculus ,Coordinate geometry consists of 25+ marks and calculus can fetch upto 40+ marks So prepare coordinate geometry +calculus +vectors(12–15 marks) .

These 3 topics will comprise 70+ marks of the paper.

If perfection supports you ,you can target for 50 .(hard task)Dont go for detailed subtopics in conics ….just basic things and few properties of tangent normal is enough. You will find coordinate difficult ,if you have not practiced it,better practice it well.

Chemistry

Prepare only these chapters which i am mentioning….

Moles+Gases+Solid state+Coordination Comp.(must)+Solution+Chemical equilibrium+P block (N-P family)+Thermo+Chemical bonding(must)These chapters will comprise around 70 marks of the total paper.You should try for atleast 55 in these.For organics Aromatic+Carbonyl+reaction mechanism +GOC+BiomoleculeThese all chapters will carry 30 marks .Overall you should try for at least 80 marks in chemistry and the key for this can be revising notes over and over with decent practice.

hope it helped.
