"CS Pooja" :
I would say go ahead and experiment (experiment is the best learning process).
As far as your following question : "Can a minor not "declare" anything?? "
WELL, Well, well, you might be surprised that the minor cannot even declare himself to a "minor", forget about anything else.
Experiment : File some issue against the School and the Student for declaring self-details on the SSC Form. The school in fact can be charged for "Intimidation" and "Breach of Trust" for violating various provisions of various laws (like contract act and Tort's), for compelling the Student to fill up declaration forms.
See if the court holds the students declaration against him in ANY manner or if the student can be prosecuted for any offence. OR even sent to the "juvenile home" for "null & void" declarations. Also see where the School lands up.
Divya Paras (Corporate Lawyer), above has described the issue quite clearly. Use it to LEARN, as a student.
