bill did not study hard . as the exam drew near , he was afraid . there was so much to study that he did not know what to start with . in the end bill failed his exam . but he learnt an impressive lesson ; a good way to pass an exam is to work hard every day . one may fail in an exam if he is lazy for most of the year and only works hard a few days before the exam . one should study hard and be diligent every day .
