Hi

Attempt limit for JEE mains

One  can give JEE Mains entrance  examination  for a maximum of 3 consecutive years starting from the year of passing 12th board examination.

Now,

JEE Main entrance examination  is conducted twice a year i.e January and April session.

So,  the maximum number of attempts for jee mains entrance examination

= 2 times *3 years

=  6 attempts in total

Attempt limit for neet examination

There is no attempt limit for neet examination one can appear in neet as  number of times as he or she wants

Thankyou
