The Ministry has sought a clarification from DU's Vice Chancellor Dinesh Singh about the arrangements made after the varsity's academic council this week cleared implementation of the scheme for the coming session, said Ministry officials.
The communication to the varsity, they said, is to ensure students are not "misguided" about their future and the preparations made.
A University spokesperson, however, said they have complied with the instructions of UGC on the system but maintained that they were unaware of the Ministry's letter.
In a communication to the vice chancellors on January 8, UGC had laid down a set of guidelines and had asked the universities to act on them for implementation of the scheme.
