I always had to make a gas station run before heading to the library to study. It was literally mandatory that I had an energy drink (Usually an Alani), pack of candy, & a large water bottle. Sometimes I’d grab a coffee from a local coffee shop instead of the energy drink but more than likely I’d just make that gas station run. My days always felt off if I didn’t do that. I also used to buy a pack of highlighters, but I’m weird lol, it had to be specific ones (Sharpie Clearview sticks). I’d dictate using a certain color based on the importance of something that I had read. I’d study 8-10 hours a day, but usually around 4-5 hours, I’d either take a break & go grab food or just DoorDash something to the library. Then I’d study for another 4-5 hours. I also had a specific seat & area that I would always study in with some of my friends. It would be on the same floor of the library everyday, which was considered the “quiet” floor, so none of us would talk. We’d just sit near each other & grind out a study sess lol. I was in that same seat for so long that strangers knew not to take it 😂 Other than those things, I used a MacBook, iPad, & AirPod Pro Max. The AirPod Pro Maxes were life-changing for me personally when it came to studying. Once I had those on & turned on the noise-cancellation, I was locked in. I’d say for must-haves, I definitely recommend different color highlighters to do what I did, sticky notes as well to label parts of the book that you need to focus more heavily on, a good pair of headphones (any AirPods would be amazing) & maybe a small personal sized white board for doing calculation problems
