Hello aspirant,

There is no guaranteed indicator as to what marks you can score if you do the mentioned chapters. You can check out the chapter wise weightage for Chemistry and focus and revise chapters that have a high weightage, though each chapter has its own importance-

CHEMISTRY-

Basic Concepts of Chemistry:- 1 %
Structure of Atom :- 2 %
Classification of Elements & Periodicity in Properties :- 2%
Chemical Bonding and Molecular Structure :- 5 %
States of Matter: Gases and Liquids :- 2 %
Equilibrium :-6 %
Thermodynamics :- 8 %
Redox Reactions :- 3 %
s-Block Elements :- 2 %
Some p-Block Elements :- 2 %
Organic Chemistry: Basic Principles & Techniques :- 4 %
Hydrocarbons :- 3 %

Solid State :- 2 %
Solutions :- 5 %
Electrochemistry :- 2 %
Chemical Kinetics :- 3 %
Surface Chemistry :- 2 %
Isolation of Elements :- 2 %
p-Block Elements :- 5 %
d- and f-Block Elements :- 4 %
Coordination Compounds :- 9 %
Haloalkanes and Haloarenes:- 3 %
Alcohols, Phenols and Ethers:- 4 %
Aldehydes, Ketones and Carboxylic Acids:- 4 %

In chemistry, chapters included in Physical Chemistry such as Thermodynamics, Equilibrium, Structure of Atom and others are completely formula based and 30% theory, so you should try doing numericals from it. Do not leave chapters like biomolecules, polymers and environmental chemistry.
