3 and a half ?

No way, you need at least 5 - 6. There's no use trying to study when you are sleep-deprived, your brain won't remember anything. It needs rest, you need rest.

9th and 10th stds aren't too difficult if you study the portions taught the same day, everyday.



marks don't depend on study alone - it depends on the ability of your brain to absorb and reproduce whatever u study, which will happen only when ur brain is fresh and rested, not groggy and sleep-deprived.What is the minimum duration a teenage girl(9th std) has to sleep%26gt;%26gt;?
either a boy or a girl have to sleep minimum of 8 hrs daily.it is not a hard and fast rule .
you should actually study spelling.

but to answer your question, you should get at least 8 hours of sleep to get the best energy to last you through the day. if you deprive yourself of sleep you will eventually get exhausted and then health problems and risks may arise.
It's better 6/7 hrs daily.
No, it is not okay. It is just not acceptable to sleep so little. The average person needs 8 hours of sleep per night and you are a teenager so your body is developing and you should get a little more than 8 hours. Your studies will definitely suffer if you are sleep-deprived so you are not doing yourself any favours. You won't retain information and you won't be able to concentrate well.
One What do you mean STD, do you mean sexually transmitted disease? and 8 hours is the best system I find, plan for it every day and mabye one day feel free to sleep in on weekend.
