Hello, you can enroll as a private student in any of the school in your state and give your 12th exam without attending regular classes if you have passed you 10th and satisfy the age limit. Also for degree programs you can do postal education where you will be provided with the syllabus and notes and you need to physically present only for the exams.

Hope this helps.
