Is neet exam is held twice in a year?

Hi

No, as of now your Neet examination is not conducted twice a year

It is only conducted once in a year and considering that only one attempt  will be there for Neet 2021,if there are any changes made in the number of attempts for neet just like this year NTA has increased the number of attempts for JEE mains from 2 to 4 times a year, and it gets conducted more than one time then NTA will notify about it  in advance but as of now there is no information as such and it is expected to be conducted only once.

NEET examination is normally conducted on the 1st sunday of May every year, so considering that your neet 2021 examination is expected to be conducted on 2nd May 2021 .

But yes,
There are  also  chances that your neet 2021  might  be   delayed   due to covid, also because of delayed events of neet 2020 , for example  delayed neet 2020 counselling ,  so these things may cause delay in neet 2021 but this cannot be said with surety , so for now we need to wait for  the notification from NTA regarding   the same

Till then you  should focus on your neet examination preparation , go well through the chapters , solve  numericals and mcqs after finishing each chapter , follow a timetable   to avoid wastage of time and once you are  done with your neet syllabus focus  on  revision  and  then  go through previous  year  question papers and mock test papers.
