For youngsters, According to Jayaprakash Gandhi, a career counsellor based in Salem, Tamil Nadu, while a kid should not spend more than four hours in school till class five, an eight-hour school day is excellent for senior secondary and secondary pupils. The younger you start, the more hours you will need to put in. The average high school student studies for about nine hours per day, five days a week. They should be studying for 12 years starting when they are very young. That's why we have university students who are already in their 30s and still haven't finished college. Students who stay up late watching TV or using social media instead of studying risk ruining their chances of getting into a good college and delaying their future careers. It's better to study for three hours daily than nothing at all. According to recent studies, teens should not study for more than six hours a day. Studies show that teenagers who study for more than 10 hours a day are more likely to suffer from depression and anxiety. So, the answer is that they should study for between three and six hours daily depending on their age.
