Heya!! Yes I use a revision timetable, however it's pretty relaxed and I'm quite often not wanting to do something for a subject and will another subject or something else instead! It's super helpful because it keeps me accountable as I can log my hours of revision on it and on top of this helps me pick out what I'm going to do on the day, rather than procrastinate and think of what to do!!! I've never been a huge procrastinator, however I make sure to stick to it by leaving notes around on it (It's on a google sheet so easy to customise and change!) for motivation or to remind me of my goals and the effort I need to put in to achieve them!
Hope this helps!
