Hi, passed out from DU in 05-06 batch. Didn't clear one exam from First Year examination. What can I do to get a DU degree right now?

I enrolled in BA Pass course in 2003 and cleared out in 2005. However I could not clear my First year exam of BDP, neither in second and third year as well . I had cleared my three exams with an aggregate of 40%. Besides my BDP subject has been discontinued now and I need to have a degree to do MBA.
