Sunil,
Based on your response this means that you have used The PM PrepCast in order to prepare for your PMP exam BEFORE you passed your PMP exam.
You can only earn PDUs for activities that you participated in AFTER you passed the exam.
And even if you claim "I didn't use the PrepCast for PMP Exam preparation", there is no way that you could earn 35 PDUs in 1 day...
Please go to
www.pm-podcast.com/pdu
and learn about the 30 free PDUs that I offer over there.
