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

During my PTE Academic test, I noticed that fatigue really hit me hard in the Listening section. Despite feeling confident in practice, the real exam's length and intensity made it tough to maintain focus. I found myself missing details that I would have caught easily before. This experience taught me the importance of pacing myself and taking mental breaks during practice to build stamina. Has anyone else experienced a drop in concentration during the test, and how did you manage it?
