Dear Aspirant,

The JEE Main  exam, is a national level screening test conducted every year to offer admission into B.E, B.Tech, B.Plan and B.Arch programmes. The National Testing Agency has decided to keep two sessions of the JEE Mains from 2020.

The JEE Mains 2020 January Session entrance test will be conducted from 6th to 11th January 2020. The April Session exam will be held from 3rd to 9th April 2020. The Admit card has also been released.

Now, for the preparation, both the 11th and 12th grade chapters are given an emphasis. The 11th grade concepts are extremely pivotal for the examination.

Here are couple of important chapters from each subject that should be paid attention to:

1) Chemistry :

a)General Organic Chemistry

b)Isomerism of Organic Compounds

c)Chemical Equilibrium

d)Ionic Equilibrium

e)Electrochemistry

f)Chemical Kinetics

g)s and p block elements

h)Redox reactions, Mole Concept and the concept of equivalents

i)Thermodynamics

j)Classification of elements and periodicity in properties

2 ) Mathematics :

a)Calculus Functions( Maxima and minima, Definite Integration      ,Area under the curve and Differential equations)

b)Algebra (PNC, Probability, Sequence and Series)

c)Coordinate Geometry (Circle, Parabola, Straight lines)

d)Trigonometry

e)Statistics

f)Matrices and Determinants

g)Vectors

3) Physics :

a)Magnetism

b)Modern Physics

c)Nuclear Physics

d)Rotational Dynamics

e)Heat and Thermodynamics

f)Fluid Mechanics

g)Vectors

h)Units and Measurements

i)Current Electricity

Hope this helps. All the best!

The important chapters in preparation of JEE MAINS doesn't change. It is the ratio of the questions given from a chapter that changes. The common important topics in mathematics, physics and chemistry are:-

From mathematics,

Differential calculus, Co-ordinate geometry, Trigonometry, Integral calculus, Vectors, 3D algebra, Matrices and Determinants

From physics,

Modern physics, Ray optics, Wave optics, Electrostatics, Electromagnetic induction, Alternating currents, Current electricity, Thermodynamics, Gravitational and rotational mechanics

From chemistry,

Chemical bonding, p-block elements, co-ordination compounds, Alkyl halides, Alcohol and ethers, Practical organic chemistry, Mole concept, Ionic equilibrium, Thermochemistry, Surface chemistry and Electrochemistry

Hope this information helps you dear students.

Wishing you a good luck!
