The exam is done twice a year and hence most candidates have an average of 4-6 attempts depending on the time of entry.

Understanding NDA Attempts: The Real Rule

The NDA does not have a strict limit of attempts as most other competitive exams do. It implies that the candidates can take the exam several times without worrying about having a limited number of chances.
Nonetheless, there is a condition of this flexibility. The age requirements indirectly regulate the number of attempts. The eligibility age bracket is also narrow and thus the candidates are only allowed to take the exam within that particular timeframe. This is why it is essential to plan your efforts well and prepare in time with the help of the appropriate nda books and a systematic plan.
