Official Syllabus for NATA 2021 – New Exam Pattern and Updated Syllabus
Published on : 18th March 2021 Author : Himanshu Basant Bhatt
National Aptitude Test in Architecture (NATA) is conducted by the Council of Architecture (COA) for admission to the first year of 5 years B.Arch. degree course offered by the recognised institutions across the country. The actual admission is done by the concerned authorities/institutes on the basis of the NATA score. In the article here, we are covering the NATA exam pattern and syllabus in detail.
Changes in the NATA Exam Pattern 2021
The following changes are introduced in the NATA exam pattern w.e.f. 2021:
 A variety of questions such as Multiple Choice Questions, Multiple Select Questions, Preferential Choice Questions, and Numerical Answer Type Questions are added.
 The number of questions will be 125 and the maximum marks will be 200.
 A combination marking scheme is adopted with questions carrying 1, 2, and 3 marks.
 There will be no drawing test.

Now, let’s have a look at the detailed syllabus for the National Aptitude Test in Architecture.
NATA Exam Syllabus for 2021
As per the official FAQs section for the 2021 exam, “Unlike any other entrance examination, NATA is an Aptitude test that assesses a candidate’s innate ability through a variety of testing formats and cannot be taught, learnt or induced. Hence, there can be no fixed syllabus or pattern as aptitude can be measured through various testing formats/techniques. Aptitude will be tested for the chosen field of study, which in this case is Architecture. ”
However, here is the previous years’ syllabus which can help students to get an idea for preparation.
