In the information bulletin published by CBSE on its website, it was mentioned that the candidates who have already appeared in AIPMT/NEET on three occasions are not allowed to take this examination.
It is now clarified that since any new regulation takes effect prospectively, NEET-2017 shall be counted as the first attempt for this purpose irrespective of the previous attempts in AIPMT/NEET, subject to the upper age limit. CBSE has been advised to make necessary corrections in the information bulletin and on their website cbseneet.nic.in ¬so that any application is not rejected on this ground. Data pertaining to applications already rejected will be erased so that rejected applications can be filed afresh.
