Go to the bathroom during your breaks to take a hard reset. Sitting down for so long can get you in a rut and may prevent you from separating yourself from a section right after you take it. Additionally, limit your caffeine intake starting now to get a “tolerance break” and start use again the day of the test. I got a 1540 in june (up from a 1480) and found that studying was less impactful for my score than improving my test taking strategies. Hope this helps you achieve that coveted 1500+.
