Also whatever your brilliant-ass cheating scheme is, your TA has probably seen it 27 times already.
Also that thing where you go mess up the headers in an empty or irrelevant file and pretend your homework got corrupted to buy yourself an extra day was invented pretty much at the same time as electronic homework submission.
Also your mileage will vary depending on the book/edition, but a lot of times a "new edition" of a textbook is just a transparent cash grab by the publisher and is 99% the same material with different page numbers, so it's worth asking the prof/a TA if the previous edition is pretty much the same. You can generally get "outdated" editions of a textbook for startlingly little money. Like I'm talking sub-$5 for a book that's $140 new sometimes.
When I was a TA for a gigantic intro class they'd just released a new edition of the book we used but they'd only sent us two desk copies (publishers send free copies to professors who teach out of their textbooks), and the class was run by a professor and three TAs, so the TAs all had to share one copy of the new edition and taught out of the old edition 90% of the time. They'd only changed one chapter, so the professor scanned that one chapter to PDF and we handed it out to anyone with the old edition.
We also had, for some reason, like five boxes of the old edition under a desk in the department office and gave them out to anyone who would take them. You can hardly give old editions of textbooks away.
Having at least a few hours of sleep between all that shit you studied and your test will get better results than pulling an all nighter to study like 4 more hours. First of all, your brain sucks balls at information storage and retrieval when you're exhausted. And second of all, sleep is when your brain organizes all the new info you picked up, so you will actually remember more of what you studied after you've slept.
Sometimes I pick something arbitrary to look forward to. Like, make a reservation at a restaurant with great desserts for 3 weeks out or something and look forward to that. Or decide I'm gonna be excited about Amazon announcing new hardware in September because maybe we'll get more kindles with USB C charging.
Also, like, adult humans don't do so good if they only get to sleep for an hour or two at a time. I don't have kids but I have a puppy and my mental health improved 10x when he stopped waking up every night because he needed to pee. Just going from two 4-hour blocks of sleep to one 8-hour block.
Then he hit puppy adolescence and had a massive sleep regression and I was getting an hour or two of sleep at a time between SCREAMING PUPPY INTERLUDES and promptly lost my fucking mind. I gave up on crating him because I needed the sleep.
"But it's not actually scary!"
Yes, I know, that's why it's a disorder and not just being a reasonable person who's afraid of frightening things!
Do you guys have ghost kitchens over there? Because there are several dead-seeming restaurants in my neighborhood that are actually just ten different restaurants on door dash and never appear to have actual customers because they just have delivery people running in and out.
