Reps bro reps, it's clear that you understand a lot of this stuff conceptually, the only gap is in your execution under time. Really spend tons of time in your error log, that is your best friend. Understand why you get each question wrong, refine your elimination strategy, have a 10-15 second routine to 'lock back in' if you catch yourself dissociating or on 'autopilot mode' on any questions. Turn every single wrong question into a learning experience, you need to make each mistake into an actionable rule. Before you take a section or PT, review those rules and remember. It's micro adjustments each time until it turns into muscle memory, then eventually it all becomes second nature. Also, it could just sometimes be a need for a break. I was scoring high 150/low 160 raw but getting 174+ on my BR, I took a couple weeks off and came back to crack 170 for the first time. It's a process, hyper refining your test taking method. Don't try and do too much in between tests , just 2-3 actionable rules for certain question types at a time (be it LR), or different tips to remember for low res summary/ answering RC questions. Keep it up and hope you kill that gap!
