fosiel9510, thank you for your course review. When you first encounter AXI4, the structure can feel complex, but if you focused on 'the process of gaining hands-on understanding of operational flow' rather than theory in Season 2, you're learning it properly. Although you're only at 30%, you're at the point where the flow is starting to come together, so if you complete it to the end, interface design will become much clearer and more organized for you. Enjoy your studies!
