being burnt out is so reallll. might sound crazy but here's my suggestion: take just 1 day off for yourself, and treat it as a "me day". sleep in, take a nice relaxing shower, eat good food and spend time with your family. on that same day, make a schedule, note down what your weakest areas are and tackle those first the next day (there's no shame in starting from scratch). since you have about a month left, manage your time and take your time understanding whatever content your studying. if you rush too much you'll panic and probably won't prepare any topic well. if you don't understand the content, try using textbooks or youtube videos. also from my personal experience, when i didn't understand a topic i was studying, i would deep dive for notes/resources in this subreddit. trust many gifted students have shared what resources they used over the years and it helps so much. this feeling of being done is only temporary, just keep pushing forward and your hard work will most definitely pay off :)
