PROCRASTINATION STUDYING TIPS PLS

For academic achievers, I need your tips. I'm so fucking desperate right now. What are your strategies when procrastinating for big tests for the next day? Like I've seen people doodling while memorizing...

So, I have 2 long quizzes (both bioscience) tomorrow morning, with first one covering all the lessons for the preliminary exam. Mostly requiring memorization. I also have 4 pending activities to complete today and PE class from 5-7pm later. All these shits making it hard for me to focus on my study. I'm on medication too so I feel always sleepy recently, easily distracted and anxious. I don't think I'll be able to ace the test if I stick to my usual study strategies. I feel like shit right now. ☹
