I have cleared my B.Tech in 2016 from MDU, Rohtak but my course duration is 2009-2013, what will be my passing year?

Hello Diamond, Your year of passing remains 2016 when you must have cleared last of your backlogs. You can call yourself from the batch of 2009 since you joined then but as you cleared your last paper in 2016, it is your year of passing. Best wishes to you.
