NATA

The overall pass percentage in NATA typically ranges between 70% and 90%, depending on the year and the specific test attempt.

For example:

In recent sessions, over 80% of candidates cleared the exam.

The pass percentage is generally high because the qualifying mark is 70 out of 200, and there is no negative marking.

However, qualifying NATA doesn't guarantee admission—higher scores are needed for top architecture colleges.

The NATA exam is scheduled from 7 Mar to 28 Jun. Candidates are required to appear for the entrance in order to participate in the entrance-based admission process. Candidates are required to clear the cutoff set by Nehru School of Architecture to get invited for the next admission rounds. 
Candidates who clear the admission process are eligible to pay the course fee and secure their seat. 

For admission to its BArch programme, the Nehru School of Architecture accepts NATA results. The NATA cutoff percentile for candidates in the General All India category was less than 90, following the previous year Nehru School of Architecture cutoffs. A candidate with a 90 percentile can thus be admitted to Nehru School of Architecture based on the cutoff pattern from prior years. 

Yes, Ganga Institute of Architecture and Town Planning accepts NATA for admission to BArch programme. However, it is not compulsory to have a NATA score for admission. Aspirants with a valid score in JEE Main Paper-2 can also get admission in BArch course. Besides, aspirants should also fulfill the eligibility requirements for admission.
