According to the discussions, for students who go to bed late and do not get enough sleep, one reason is because they do not prioritise their homework and finish their other stuff instead, leaving homework to the last minute and having them to stay up all night to finish their homework or assignments. Another reason is because they reach home late, as their CCAs and remedials end later than usual and the students’ home is very far from the school. Students also stay up late to play games and visit social networking sites and end up not being aware of the time. We have found this out through the surveys that we held and students have provided us with the above stated information in their answers to the questions.According to the survey done, if they do not have enough sleep, they cannot keep up in class, cannot concentrate and pay full attention to the teacher. They also feel that their performance is becoming worse compared to the start of the year.
