Greetings aspirant!

The process of applying for dummy schooling varies from school to school. You can contact the school you wish to take admission in and discuss the procedure it follows with the faculty. Usually they ask you to do the required documentation which again varies with different schools. You may consult the terms and conditions with the administrative staff if any and make a wise choice.

Dummy schools differs from regular ones, as they don't require you to go to school daily. These are mainly preferred by JEE/NEET aspirants. While many dummy schools take care of attendance, some also manage marks for internal examinations. A minimum of 75% attendance is essential to appear in CBSE examination. Dummy schools help maintaining the number without really asking the student to come to school. It gives time to students to attend coaching for JEE/NEET prep. It aids students to focus on their preparation without worrying about the school homework or assignment. Nowadays many JEE/NEET aspirants prefer dummy schooling. These schools just require you to come on some specific days to fulfill the formalities. You might be asked to appear in some important exams or practicals (as the case maybe), otherwise you can devote your 100% focus to the coaching/JEE or NEET preparation.

In case you wish to apply for dummy admission, consult the administrative staff of the respective school and do all the required formalities. Note that there is no common process for dummy admission,  so do talk to the faculty at the schools about the procedure they follow.
