Hello,

I hope you are fine student. Do not worry. I will try to list out some sources and I hope they work for you. You can start teaching online if you have any students or you can even approach students and ask them, you can do some freelancing jobs go on google for many sites. There are also online teaching platforms like Unacademy or Chegg etc where you can teach many subjects. You can also use platforms which solve doubts of students. Check out Intershala for internships and work from home.  Make sure yoy have trusted sites only and not anything. Do pay attention to what you work for. Thanks and all the best to you
