My Certified Pega Business Architect 8.8 - Help

I have just failed my Pega BA 8.8 Test with the below scoring, I ran through all the BA Missions passing every time but feel like I have missed some Modules to get such a low score.

When doing the test I found nothing similar and found the case study very different, can anyone help me share the correct link to each module and what else I can do to prepare for my next upcoming exam?

@GiorgiaC16646448 did you already go through the 'How to prepare for a Certification Exam’ question on the Pega Academy FAQ pages?
