TOPIC: PMI ACP exam syllabus 2018

Hi,

I'm interested in the Agile PrepCast and would like to start my study in early 2018. As far as I know, there would be some changes on the exam syllabus on 26 Mar 2018. My question is that should I purchase the PrepCast after 26 Mar 2018 as probably I would like to take the exam after Mar 2018.

What if I purchase the PrepCast and start my study in early 2018? Do I need to purchase all over?

Thanks!

Best regards,
Teddy
