Yes, it's good for older children to decide their own study routines because they know what works best for them. They can choose when and what to study, which helps them be more responsible.

No, I don't think older children should always decide their own study routines. Sometimes they might choose to hang out with friends instead of studying, which isn't good for their education.

It depends on the child. If they are mature and know how to manage their time, then it might be okay. But if they are not very disciplined, parents might need to help them out.
