Hello Dear,

Learning is a continuous process you can pass class 12 through various ways but best ways is to appear through National Open Schooling (NIOS) for Senior Secondary Course. You have to choose five subjects of any combination and English as one of the subjects. Examinations are conducted like normal board exams. Some study centres conduct regular classes for NIOS students for little fee. You will have to submit assignments which are evaluated and marks are assigned to it. Certificates form NIOS are valid in all over India.

Good Luck
