Hello Kishan,

Following are some of the best books for preparation of JEE Advance -

PHYSICS:

• H.C. Verma: This book is the Bible for IIT JEE physics. You have to be thorough with each and every word of the theory in this book. Also, solve all the objective and short answer questions with diligence.
• Cengage (by B.M Sharma): This book is excellent for both theory and problems. It will teach you many new concepts, which you will be able to appreciate after being thorough with Verma.
• Purchase a very old edition of D. C. Pandey’s physics for IIT JEE. (the pre-2006 books containing only subjective problems). Solve this book.

CHEMISTRY

• The official NCERT books are extremely important. Complete them from cover to cover.
• For physical chemistry, refer to NCERT and Cengage for theory. Also, look at OP Tandon physical chemistry. Solve problems from Cengage. 
• For Inorganic chemistry, be extremely thorough with NCERT. After that, take a look at Cengage.
• For organic chemistry, no book beats Morrison and Boyd. Read all the topics of the IIT JEE syllabus from here (after completing NCERT).

MATHEMATICS 

The only key to master Mathematics is to practice a lot. Also, you need the ability to independently solve tricky problems.

• “Problems Plus in IIT JEE Mathematics” by A Dasgupta and “A Course in Mathematics for IIT JEE” by Tata McGraw Hill ( the 4th edition of the year 2000) are very important.

Good luck!

Jee advance will conduct for PCM group. So for physics best book is concepts of physics. R.S. Agrawal's maths book is good for maths. And for NCERT's Chemistry is one of the good book for the chemistry. You can make use of online vedios to clear concepts along with this books. NATA is conducted on three sessions , aptitude , maths and drawing. To prepare all the sessions architecture entrance guide is good.

I hope it will help.

Thanks.
