Be realistic! - Don't make a schedule that's too inflexible, as you're less likely to follow it. If you know you're not an early bird, don't schedule your revision to start at 7am, as it will be hard to stick with.
Set long and short-term rewards - After a certain amount of study, treat yourself to a coffee break, chat with a friend, go to the gym, play a game, eat a cake (in moderation) and keep your long-term reward in mind - to do as well as you deserve in the exam by being properly prepared.
Achievable goals - Have a to do list and tick off what you've completed as you go along to keep you motivated
Alert times - Pick the times of day when you're most alert to do your revision, not everyone is the same!
Time on/time off - Try studying for 50 minutes, then take a 5-minute break so you don't overload yourself.
Be flexible - Don't worry if you wake up late! Adjust your plans rather than writing your day off.
