Hi Guys, I'm a developer and has 5 years for coding, i have experience about the full-stack. Now I'm a Product manager.

Before I have a little bit experience about the Analysis and Agile Scrum. 

The question is: " I ask some the agent who supplier these course for IIBA certification, so they said to me that I need to start from the beginning to learn IIBA. Do I need to start to begin?
