Hello Aspirant,

National Aptitude Test in Architecture (NATA) is being conducted by COA( Council of Architecture ).The purpose of conducting NATA is to provide a single scheme of examination for holding aptitude test and to facilitate prospective students all over the country to apply for admissions in architecture seats in institutions spread across the country and to avoid appearing in multiple aptitude tests.

The NATA also ensures that the eligibility criteria for admission to five year Bachelor of Architecture (B.Arch.) degree course, as prescribed by CoA and duly approved by the Central Government, are strictly adhered to and followed all over the country in Architectural Institutions.

• CoA has further decided to conduct the test twice a year(from 2019), thus giving opportunity to those students who miss out the first test due to some reason or other and to improve upon their NATA score in the first test by re-appearing the second test .
  

Revised Eligibility Criteria:

• No candidate shall be admitted to architecture course unless she/ he has passed an examination at the end of the 10+2 scheme of examination with at least 50% aggregate marks in Physics, Chemistry & Mathematics and also at least 50% marks in aggregate of the 10+2 level examination or passed 10+3 Diploma Examination with Mathematics as compulsory subject with at least 50% marks in aggregate. (those appearing the 10+2 exam with PCM  subjects in the
  current year may also provisionally appear in the exam, however, their result in NATA-2019 will
  be declared valid subject to fulfilling the above criteria).
  

The revised eligibility states that you have to score atleast 50% in all the subjects(physics, mathematics,chemistry) individually and also score atleast 50% with all the subjects put together. Since you didnot score 50% in mathematics, you didnot meet the required eligibility criteria and hence, you are not eligible for applying for NATA Examination.

For detailed information regarding the eligibility criteria, read the brochure in the link given below:

Hello. To be eligible for NATA 2019 you will need to score 50% in physics, chemistry and maths in aggregate. There is no criteria for individual marks in a particular subject. So if the aggregate in physics, chemistry and maths is 50% or above then you can sit for NATA 2019. But remember that you will need to score a total of 50% or above in the qualifying exam also.

Hope this helps. For more queries feel free to comment down below.

Good luck!
