No, As of now NEET 2021 will not be conducted twice a year. Since, NEET Exam is one of the most prestigious exam of the country, the expected number of candidates applying for this exam in 2021 is > 1.5 million, clearly which makes it a cumbersome process for the National Testing agency to conduct multiple times a year.
The same rumours were being Outbursted in the year 2020 for NEET being held twice a year but eventually National testing agency cleared this by releasing the NEET 2020 prospectus, which stated that NEET will be held only once in 2020 (Pen paper mode/Offline).
So, some students were expecting that NEET will also be held multiple times a year, but as of now there’s no such official update by the exam conducting body (NTA) on this issue.
Our education minister Ramesh Pokhriyal Nishank is constantly communicating with students via video conferencing on a regular basis, many students have demanded NEET Exam to be held multiple times a year
