Dear Neha, As per the new conducting authority, National Testing Agency (NTA), there is limitation in attempting NEET entrance exam. The earlier exam conducting body, Central Board of Secondary Examination (CBSE) stated on the official CBSE NEET website, "There is no cap for the number of attempts". The CBSE has also cited the Ministry of Health and Family Welfare's letter no. U.12023/16/2010-ME-II dated December 6, 2017 for this. So this is the official rule for NEET 2019 till now, that there is no longer any cap on the number of attempts.

The three limit rule was introduced by the CBSE in the year 2017 but no longer applies. Therefore, all candidates can appear for NEET as many times as the upper age limit rule (check next section) permits them.

All the best 

Hope this helps
