No.. I liked the others books of Arihant which made me buy this.. there are countless number of mistakes in the solutions. I started to by heart the questions of the answers which I didn't know, and then i attended a mock test and I don't even know how much negative I got because of this book. And regarding the answers of figure related questions, it is hard for you to even search for the answers one by one on Google. Folding figures, as far I have the nata previous papers, the one in the book is way higher level.

Hii..

There are books by Arihant which you can refer for Aptitude and Drawing.

Apart from that you get a lot of books online, I'll list a few of them :

• NATA & B.Arch Question Bank  by Ar. Shadan Usmani
• NATA & B.Arch complete self study material: entrance examination by  Ar. Shadan Usmani
• A Complete Self Study Guide for B.Arch by P. K. Mishra
• B.Arch Entrance Examination Guide by Surendra Kavimandan

Hii Sravani

Yeah almost all the books of Arihant publications are useful for various entrance examination but you should not be dependable on a single book. If you wanna a good rank in NATA then try to refer other books too as a reference as well after completing the book start solving the Guess/Model paper which will improve your efficiency and time skills. 

All the best
