The resident doctors have also extended their support to the agitation and would be joining the students during the demonstrations, he claimed.

"Only OPD services would be affected and other services would be normal to ensure that patients do not suffer," he added.

Maulana Azad Dental College and Hospital principal Dr Mahesh Verma, however, said, "The students and the resident doctors are on a one-day token strike."

Some students have also decided to boycott the ongoing exams of the second and fourth semester, Lochan said adding, "It was their individual decision."

"We have not yet decided on boycotting the exams, but some students are doing it on their own," he said.

Medical students clashed with the police on Wednesday when they were stopped from moving towards HRD Minister Arjun Singh's [Images] residence to register their protest against the Centre's proposed move to increase OBC quotas in eductional institutions.
