PMDC Bill is delayed till "unknown Date". Bill was expected to be in auto mode and to be passed in senate on urgent basis but Govt is not taking it that much serious.
We will suggest students to prepare according to PMC Syllabus and don't waste time on Politician's false hopes.
Be ready for NMDCAT...
