what is the last month to submit pdgca assignments?

Hello,

You haven't mentioned the name of the university, in case you're enquiring for PGDCA assignments of IGNOU, then it's semester specific, so depending upon the session in which you have taken admission you'll be required to submit the assignments, if you took admission in January session of this year then you have to submit first semester assignment to appear in June TEE, and the assignment submission date for the same is 31st May.
