Hello Aria

Here are a few good books to prepare for JEE maina paper 2.

A Complete Self Study Guide for B. Arch by PK Mishra

Modern Approach to Verbal & Non-Verbal Reasoning by R.S. Aggarwal

Steps to Architecture NATA and JEE Mains Entrance Exam Guide By R Gupta

Also solve previous year question papers. This is the best way to prepare for the exam as this will give you a clear idea about the pattern and difficulty level of the questions asked in the exam.

The same preparation will help you with NATA. The only difference would be, it has more knowledge and awareness based questions.

I hope you get my point.

Good Luck!!!
