Dear Rohit,

According to the new rules you can write neet as many times as you want.The restriction has been removed.Also the age restriction is removed that was previously 25 years.Now candidates of any age can write neet examination, just u need to be minimum 16 years of age and have atleast 50%in PCB for General category and 40% for reserved category like SC or ST. 

ALL THE BEST !!
