How fatigue affected my focus during the Listening section of the PTE Academic

During my PTE Academic test, I noticed that as I progressed into the Listening section, my concentration started to wane significantly. Despite feeling confident in practice sessions, the real exam's length and intensity made it harder to maintain focus, especially when trying to catch every detail in audio clips. This fatigue led me to miss some key points, which impacted my answers. I realized that pacing myself and taking brief mental breaks between sections might help manage energy better. How do you manage your focus and energy levels during longer exam sections?
