Re: Sleep

This is a very interesting topic. Most students spend endless hours on their books without getting the proper amount of sleep. Can anyone be kind enough to out a medical research which proves the ideal amount of rest for a teenager (12 or 13 to 19 years)

Well, I don't know an exact average since it depends on the performance of students in the year. But just to be on the safe side of gaining a distinction/one aim for 75 percent and above.
With that you can't really go wrong in getting that much. People got to do real good for that not be worth a one.
