Yes.it is sufficient to study physical and inorganic chemistry for JEE mains.

do this, will help you;

1. p Block Elements
2. Coordination Compounds
3. Biomolecules and Polymers
4. d and f Block elements
5. Chemical Bonding and Molecular Structure
6. s Block elements ( Alkali and Alkaline earth Metals) and Hydrogen
7. Electrochemistry
8. Chemical Kinetics
9. Atomic Structure
10. Alkanes, Alkenes and Alkynes ( Hydrocarbons

Dear Pranav,

If you want to score good marks in chemistry you should focus on the important topics which holds good weightage in the exam. 

You can check the important topics below

Chemical Bonding- 6.67%

S-Block- 6.67%

Alkyl Hallide, Alcohol & Ether (Reaction Mechanism)- 13.33%

Mole Concept- 10.00%

Good Luck!!

hey,

well you'll be able to attempt 20 question of chemistry. so yes you can go with it. but organic is not tough at all, what you can do is learn the reagents and their roles, or just cram it. will help you answer few question.
