Hello student we don't recommend/promote dummy school, you should get admission in a proper school in which you can go and get classes of each subject because school study is very important specially at higher secondary level you should attend school properly. Due to covid 19 second wave schools are closed in mostly state still admission process and classes are taking place online you should take admission and join classes online or as per the direction of school.

Feel free to comment if you've any doubt

Good luck
