This is what I did during my test in Aug. Use bathroom, take a few bites of chocolate, drink a couple of sips of water, close eyes and do breathing exercise.
Short! lol
You can get up, use the restroom, eat, drink, etc. You are allowed to be off-camera, you just can't use your phone. They will have you do another security scan before you resume your 3rd section.
So before I take a test or drill, I drink a small cup (like half to a quarter) and then take a nootropic for focus and memory. Really feel it helps me.
Get back at it and keep studying. I'm dealing with my own LSAT issues myself and I'm trying to quit coffee. Out of curiosity, do you drink coffee before studying or every morning? The caffeine crash is pissing me off.
I'm so happy for you! Congrats! Out of curiosity did you drink anything with caffeine in it while studying and taking the actual test like coffee for example?
