London : What’s the key to success in exams? Well, an extra hour in bed in the morning , apart from hard work , say scientists.
An experiment, designed by three British scientists which allows students to stay in bed for an extra hour in the same morning have boosted exam results and slashes absenteeism.

The scientists, led by neuroscience Russell Foster of Oxford University, found that teenagers have a biological predisposition to go to bed late and get up late particularly during exam time, and may not being to function fully under 10am, two to four hour later than adults.

The experiment also revealed that the most difficult lessons should take place in the afternoon, while pupils will be at most alert.

This adolescent “time shifts” persists until the age of 21 , after which a person’s body clock starts to swift back again until the age of 50 they are likely to get out of bed as early as when they were young children.

“Teachers will say, ‘I know my kids are at their best first things in the morning’ , but what’s really going on is that the teacher are feeling particularly awake by 9am and the kids are half asleep, making the class easier to control, ” Foster Said.
