I'm almost 3 months into my studies and my best PT is 159 untimed. Any tips on improving LR stamina and speed? I start disassociating after the first section and my focus just plummets. I can't even attempt timed PTs yet; I have never finished a section and attempted all questions. Any study tips or ways to improve focus and not experience cognitive overload? I'm trying to slowly build it up and focusing on fundamentals but wondering if there's ways to speed up the process.

For context, my diagnostic was 139 so I know I'm improving. My biggest issue isn't understanding every question but maintaining focus and processing information efficiently for multiple sections. Did anyone else struggle with this? What can help build endurance and transition from untimed accuracy to timed performance?
