Have you noticed that during the school day get times when you just don't care any longer ? I don't mean the lessons you don't like , but the ones you find usually find OK , but on some occasions you just can't be bothered with it . You have other on your mind , be tired , restless , or looking forward to what comes next . Whatever the reason , that particular lesson doesn't get 100 percent from you The same is true of revision . Your mental and physical are . If you try to revise when you are tired or totally occupied with something else , your revision will be inefficient and just about worthless . If you it feeling fresh , alert and happy , it will be so much easier and you will learn more , faster . However , if you make no plans and just in a little bit of revision when you feel like it , you probably won't do much revision ! You need a revision timetable so you don't keep it .
