What are the important chapter for the preparation of Jee (Main) and Jee (Advance) 2017?

There are some topics which are the most important and scoring topics. Ideally you should try to cover the entire syllabus well.

Physics :

1. Kinematics – Very simple questions are asked. If you keep the definitions in mind, then all questions will be easy
2. Newton’s laws of motion – Knowing how to draw a free body diagram will greatly help in solving almost all problems of this chapter
3. Simple harmonic motion – Energy conservation method will be useful in finding time period in even the most complicated cases of SHM
4. First law of thermodynamics – Knowing the statement of energy conservation will help you to solve a number of numericals and theoretical questions as well
5. Current Electricity – A good practice of Kirchoff’s law problems will help you to score cent percent in this topic
6. Radioactive decay – The radioactivity decay formula will be the most useful tool in solving almost all the problems

Mathematics :

1. Conic sections – Knowing the formulas well will help you. The parametric form is one of the most useful tool in solving problems of conics
2. Quadratic Equations – knowing the fundamental properties regarding nature of roots / intervals in which roots lie will help you
3. Progression and series – very scoring and simple chapter. Knowing the definitionsand practising ample of problems would be useful
4. Differentiation – Keeping the formulas in mind will help. Geometric interpretation of derivative is an important concept. A number of simple questions are asked which can be done with ease
5. Vector Algebra – Knowing how to visualize the situation will be useful. The concepts of vector and scalar triple products are most scoring

Chemistry :

1. Alkyl Halides – Simple questions based on reactivity / type of reactions are asked and can be cracked easily
2. Electrophilic aromatic substitution reactions of benzene – standard reactions are the most important. Direct questions are asked from this chapter
3. Chemical Equilibrium - Knowing the basic equation of equilibrium along with a proficiency in solving ideal gas equation problems will definitely fetch you full marks
4. Chemical Kinetics – First order reactions are asked in JEE and are easy if you know the basic definitions
5. Ores and Metallurgy - Standard questions are asked which can be done easily
6. Coordination compounds - isomerism is an important but easy topic and you can easily score 100% in this

Thanking You;)
