The Exam Pattern of NATA is decided by Council of Architecture. NATA will be conducted for a total time duration of 3 hours (180 minutes) and consists of 2 parts

1. Mathematics & General Aptitude Test and
2. Drawing Test

Mathematics & General Aptitude Test

Mathematics & General Aptitude test will comprise of multiple choice questions. It will be conducted in offline mode during the first half of the aptitude test for a time duration of 1 hour 30 minutes (90 minutes). The candidates will have to answer a total of 60 multiple choice questions and each question carrys 2 marks each.
Mathematics (20 Questions)- Total 40 marks
General Aptitude Test (40 Questions)- Total 80 marks.

There will be no negative marking.
Aspirants need to mark their response on OMR sheet using black/blue ball point pen only.

Drawing Test
The drawing test needs to be attempted for last 1 hour 30 minutes (90 minutes) where, candidates will be required to attempt a total number of 2 questions carrying 40 marks each. Each question has two sub-questions which will be required to be attempted by using a paper and pencil.

The drawing aptitude test is judged on the following aspects -

Scoring Process

The drawing paper would be evaluated by a panel of three examiners independently and an average of marks is taken. The primary emphasis in scoring the drawing section is on the candidate's drawing, imagination and observation skills. The candidate's sense of proportion and perspective are also evaluated together with sense for colour and composition.

In the multiple choice questions, the candidate scores on the basis of the number of correct answers that he/she gives.

During merit listing, all candidates would get unique rank. Therefore, if more than one candidate gets the same overall marks, tie breaking logic would be applied in the following order:

  1. More overall marks obtained in Mathematics test component
  2. Less wrong answers in attempted ones of Mathematics test component
  3. More overall marks in problems of Aptitude test component
  4. Less wrong answers in attempted ones of aptitude test component
  5. Earlier date of birth
