hello aspirant,

NATA entrance examination is all about 2D, 3D, perspective drawing, and also aesthetic sensitivity tests. Therefore, if you want to achieve the ideal theory or concept behind successful marks, there’s no actual book that can help in this regard. The patterns keep changing, and thus, staying within a boundary becomes a bit complicated.  You need to have several reference books for a clear discernment drawing, shade shadow, toning, etc. Getting to the advanced mode, always stay focused on the upcoming architects, building, materials used, and others.

Maths: When the question is Maths, it is suggested to go through the CBSE books as most of the sums are clearly explained. The type of Maths that comes in NATA examination is usually a lot easier than other tests.

hope that helps
