Congratulations, Gopinath! Glad to hear that you find the PMPrepCast helpful in your preparation!
Unfortunately, you would not be able to claim any PDUs for the course, if you used it to get contact hours in preparation for the PMP application.
You may want to consider other resources, such as the
PDU Podcast
, which also includes some free resources for you to preview. There are also a number of resources to get (free) PDUs on the PMI and ProjectManagement.com websites. In my opinion and based on my experience, these will offer you an actual opportunity to grow as a professional, and therefore prove your professional development as a PMP. Also, please keep in mind that - according to the CCR Handbook - part of the PDUs (max 25) required to maintain your certification may be associated to the so-called "giving back", which comes from volunteering opportunities and your work as a professional.
Hope this helps,
Gabriella
