Hi Rohit

Chemistry

Inorganic Chemistry carries a weightage of 34 %. Among all the units, Chemical Bonding and Molecular Structure carries the maximum weightage of 29.4%. All the major important topics are covered in this section. It is then followed by Co-ordination compounds from which nearly 17.6% of the question were asked on average from this unit.

Organic Chemistry carries the maximum weightage of 35.6%. From this, nearly 30  % (assuming total 100%) of the questions from previous year paper were fromOrganic compounds containing Oxygen.  Basic Principles of Organic Chemistry is the second most important chapter and thus carries a weightage of 24.4%.

This unit was given high importance in NEET 2017 exam. Accordingly, this unit carries 30.4% weightage.(Assuming total 100%) Among all, States of Matter and Solutions (24.1%) is the most important of all followed by Equilibrium (18.2%).  Rest of the questions were asked from the different chapter covering Chemical Kinetics and Nuclear Chemistry (14.6%), Thermodynamics and Thermochemistry (13.1%) and others.

Physics

last year trend was

BIOLOGY

All chapters are important. try to stick to NCERT.
