The night before this Jan 26 LSAT, I got 2.75 hours of sleep.
I tried to close my eyes at 10pm only to fall asleep at 4am. My heart was racing the whole time; it felt like adrenaline was coursing through my veins. The thought that months of prep could be singlehandedly ruined from the effect of one awful sleep made me feel so helpless. It got to the point where I woke my mom up at 3am to ask her what I should do. I fell asleep crying.
But, to my surprise, I woke up at 6:45am feeling ready to fricken rock. Any thought that ventured into the dark territory of "what if your lack of sleep slows down your thought processing?"...I ninja kicked it out of my head. I got to the test centre at 8am (forcing myself to think positive thoughts) and wrote the test feeling as sharp as I would have writing any other PT on a good nights sleep.
If anyone reads this and then come test night experiences this same involuntary alertness, at the very least you can recall my experience to feel a bit more at ease: it is possible to write the LSAT on minimal sleep and still feel confident performance-wise. Be sure to stay positive.
