What do y'all do to review for exams

Okay my thing hasn't been working lately anymore, I get distracted midread on my notes and open TikTok and doomscroll until it's too late. Basically Proscastination midway lol, seriously need to try other methods ya guys do to keep your focus because even if I delete TikTok , I open up other shit that distract me and if my phone doesn't function I open my TV or do some weird ahh chores from my neighbors
