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)

This is NOT the grade distribution

Hello, this is NOT CXC's grade scheme. The only grade scheme CXC has ever published for CXC CSEC exams is here:

ITS A CURVE

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.
