Dear Arif,

As far as the topic of who will be conducting the examinations next year is concerned, although a national testing authority (NTA) has been formed, it will take them time to come into full force and since the registrations for NEET-UG entrance will probably begin by the end of December 2017 or by January 2018, CBSE might probably intervene for the year 2018 and NTA might come into force from 2019 onwards.
Unless an official news is out, this remains a dilemma.
