Hello Mirza,
My apologies for the late response. I was in Europe for a family emergency.
The short answer is that The PM PrepCast basic is primarily a PMP exam prep course, that can also be used by PMPs to earn 60 PDUs for their renewal. The PrepCast is not specifically targeted at holders of the PMI-SP certificate. And since it doesn't cover all the PDUs needed for PMI-SP renewal we do not specifically promote and market it to the PMI-SP community.
When we add a new course to the PMI online directory we are required to calculate the exact number of PDUs that we provide for each of the certifications. You can see the calculations for all the certificates by following this link here:
ccrs.pmi.org/search/course/381379
-- The upshot of this calculation is that even though the course qualifies for 60 PDUs for PMP renewal, we can only offer 25.5 PDUs for PMI-SP. This is because the course only covers that many hours that are 'relevant to project scheduling' as PMI requires.
As Joe has already indicated, the fastest way for you to earn an additional 4.5 PDUs is by simply listening to 4.5 more hours of The Free PM Podcast. My recommendation would be that you input your earned PDUs online with PMI and then check how many technical, leadership and strategy PDUs you need. Then simply pick a few of the free podcast interviews that relate to these topics to cover what you need.
So what you see
Until Next Time,
