Hello Aspirant,

We do have JEE Knockout packages that can help you in JEE Mains preparation. You can check that at the link given below :-

Alternatively, as the syllabus is based on your 11th and 12th standard, NCERT books should be your go to books. Coordination Chemistry and Chemical Bonding are the important topics that you need to practise as much as you can. Memorise the Periodic table as much as you can. The questions asked will be conceptual, concerned with structures, processes and applications. Topics like p block elements and Qualitative Analysis are important too.

Attempt and solve as many sample papers you can along with atleast one mock test a week.

I hope this information helps you.

Good Luck!!
