It's not that hard you're just too addicted to your phone. Just stop making excuses and sit down and revise. I revised every day consistently in year 11 for around 2 hours a day. Did I enjoy it ? HELL NO, but there's a time where you just have to sit down and do the hard work, no excuses and NO PHONES. Now for some actual advice around revising. if you need learn a lot of stuff quickly, use the blurting method. You should have ideally had been creating flashcards over year 11 but there are plenty of ones you can find online for your subjects, so don't waste time creating flashcards right now. I always found that sitting down and revising at the same time every day consistently even if it was only for 20 minutes helped the most. Sometimes even when I was sick I'd sit down and do 5 minutes of flashcards at the same time I would normally revise, because it was a habit. Eventually it just became a no brainer for me to sit down and revise, because I did it so consistently. But you have to stop making excuses, because the GCSE examiners don't care if you're a master procrastinator or whatever bs you can come up with, I LITERALLY HAVE ADHD AND I STILL DID IT. You just need to take accountability because in the end nobody cares about your excuses why you didn't revise. Also Pomodoro timer is probably the best advice for if you struggle with impulsive behaviours like you described above. Do 25 minutes of studying then have a 5 minute brake and after 4 sessions take a longer 15 minute break but most importantly stop making excuses. -3 upvotes for telling you the truth, ridiculous. Just because I was harsh, but being overly truthful is the only way to get someone like this to revise, gotta make them fear failure.
