Good Luck!

Dear Suman, NTA has replaced CBSE as the conducting body of NEET UG. So unlile until last year wherein CBSE was conducting the exam, from 2019, NTA will do the needful. So to answer your question, everything pertaining to NEET will be handled by NTA. NEET 2019 will be conducted on May 5 in a single shift. The shift timing of NEET 2019 is 2.00 AM to 5.00 AM.
