The Centre is exploring the use of Indian Air Force aircraft to transport NEET-UG papers for the June 21 retest to ensure tighter security.
A meeting chaired by Rajnath Singh and attended by Dharmendra Pradhan reviewed the entire examination process, including paper printing, transport and security.
The NEET-UG exam was cancelled on May 12 following allegations of a paper leak, with the Central Bureau of Investigation arresting 13 accused so far in the case.
