I would like to know about any suggestions that the community can give about coping with online school. I have both school and my coaching classes. Hence the screen time is too high and I also require time for self study. The syllabus covered in school is the same as in the coaching institute. The teaching of my coaching is better, but attendance in school is compulsory (for internal marks). Also, currently both are through online platforms itself, so let me know how to manage my time. (School timing 6 hrs each day for 6 days a week and coaching timing 7.5 hrs in a week)
Clearly it's going to be a sub optimal use of time to attend both lessons and pay full attention. I will assume the coaching classes are happening because the school classes are sub-optimal, therefor in the school classes, you need a second activity to occupy you. It needs to be something that wont get you in too much trouble, so it needs to be strongly related to the class. Using the information in the comment;
I am studying high school level physics, maths, chemistry, social science, mental ability, information technology and a couple of languages
Of these subjects, I know that maths chemistry and physics are mainly exam based, and from almost any given exam, there are lots of past papers available. You should print out exam questions of the appropriate subject and try to work through them during class. Printed exam questions, rather than reading from a screen, so that it doesn't look like you're browsing the web.
You must be able to hear the class as you do it, and if someone asks you what you are doing, apologise and answer honestly. Say you feel you have a good grasp of the material, and want to practice for the exam. Most teachers will find this answer acceptable.
