Top tips for exam success

GCSEs can be stressful but getting stressed is no help when it comes to exam
success. The following are top tips for exam success:
¤ Create three zones for yourself.
It's important to create a Study zone, a Relaxation zone and a Sleep zone.
Keep these areas distinct and make sure the study and sleep spaces are calm
and uncluttered. Don’t revise in bed or when watching television.
¤ Plan and use a revision timetable.
Schedule time to study, relax and sleep. Break revision periods into
manageable chunks. Don’t do too much in one go. Don't do too little either.
¤ Take regular breaks.
Break your study up into twenty minute chunks. You should not study for
more than two hours without taking a break of about twenty minutes. These
short breaks should be used to unwind, chat to friends, have a drink and eat
a healthy snack. It's also important to take an extended break each day to
really 'switch off' from studying.
¤ Eat a healthy diet and exercise.
Eating healthy food and drinking at regular intervals throughout the day will
maintain your energy levels and concentration. Avoid too much coffee, tea
or 'energy' drinks, as the caffeine can make you feel agitated and stop you
sleeping. Exercising regularly helps release adrenalin, clear your mind and
reduce stress.
¤ Sleep well and ensure you sleep long enough.
Maintain a regular sleep pattern. Always aim to get at least eight hours sleep
per night and try to fit in one hour of relaxation before you go to bed.
