Dear 12 grader, since you are getting the freedom you need, you need to balance it with your responsibility. Here are a number of advice's that one can follow to keep a balance
Party on alternate weekends, this will help you to juggle between your errands and your enjoyment. Weekends should be organized in such a way that most portion of your holidays should be given to your parents. You should help them in house errands and chores, and give plenty of time to them.
In addition to that, you should not neglect your studies. Make a timetable for yourself, declare the days when you will study and follow it.
In the end, I would suggest to always plan your day. So not only you can fulfill your responsibilities that you have towards your studies, parents and country, but also enjoy your day by hanging out with your friends, playing games etc.!
