Hello Nihal Kaushik. Thanks for contacting Careers360 and we hope we will be able to answer your query.

You can easily get 30 marks in JEE Mains. Want to know how??

The JEE Mains chemistry paper usually has hardcore facts on inorganic and biochemistry which are there only in NCERT. So, I would please advice you to study your NCERT / CBSE class 11 and 12 syllabus line by line.

Also please read chapters like:

• Coordination chemistry;
• Electrochemistry;
• Redox etc. 

where atleast two questions appear in the exam. 

Please be assured that the questions are not very difficult in chemistry if you study NCERT thoroughly.

Hope this helps you and all the best!
