National Aptitude Test in Architecture (NATA) is conducted by the Council of Architecture (COA) for admission to first year of 5 year B.Arch Degree course at all recognized institutions all over the country. The test measures drawing and observation skills, sense of proportion, aesthetic sensitivity and critical thinking ability. This is a complete and comprehensive assesement of candidates for undergraduate education in architecture. Admission to all architecture colleges (including government, government-aided, private unaided, university department, deemed universities) in India is done on the basis of NATA score.

NATA 2021 Preparation:-
There are no shortcuts to success. One has to strive a lot in order to achieve success in NATA exam. Aspirants who will be appearing for NATA must realize that it is high time they start preparing for the exam. Joining a good coaching class will surely get you a good result but, if you are not interested in it, then you can refer to some books of architecture and those specially designed for architectural entrance like the ones illustrated below:
• Architecture Entrance Book by P. K. Mishra
• NATA Examination ( Verbal / Non- Verbal / Reasoning ) by R.S. Agarwal
• NATA Entrance Examination by Arihant Book
Besides this, make a proper list that distinguishes famous national buildings and international buildings. The reason behind this; there is a probability that you might asked to spot the structures. You should also solve previous year’s NATA papers to have fair idea about the types of questions asked in the exam.
