Hello ,

Hope you are doing good

By easiest topics I am assuming that topics that have direct formula based questions  and which have more weightage.

Topic Includes:

Solid State as it is small chapter

Organic Chemistry try to go through each reaction in NCERT as direct questions are asked from textbook itself

Hydrogen

Physical Chemistry

Polymers

Surface Chemistry

Chemical bonding and Mole concepts

Chemistry in evryday life

Periodicity

Structure of Atom

If you have prepared well for your boards than chemstry would not be a burden for you .

All the above mentioned topics are quite easy and important it will help you to achieve good marks.

Hope it will help you

Thankyou

Goodluck!!

Dear Aspirant,

You can not prepare enough in 15 days if you have not studied chemistry at all. In this case I would suggest you should give NCERT regular readings, and solve previous year papers. Keep on solving the chemistry section from the last 10 years, do it twice, thrice, as long as you can.

This will build a muscle memory and make you familiar with the concepts in a paced way.

Hope this helps. Thank you.
