Hello Pratham,

If you had failed in more than one subject ,then you cannot clear your 12th in the same year.You need to apply for 12th board again,if there are practical you have to clear those exams also.You can go for a private student,where one does not need to go school,you have to only go for writing your exams.You can sit at home and study . There is compartment exam,but that is only if you have failed one subject.Don't lose heart ,it happens with many students.Prepare this time well.

All the best

Hello student I'm considering you as a cbse student in cbse you have a option for compartment exam if you failed in one subject. Once you clear your compartment exam then you'll get your certificate and you'll pass your class 12.if you don't want to appear in the same board exams then you have option of nios which is an open board and also recognised board you may clear your +2 from nios and save your year.

If you want to repeat your class 12 then you have to apply again for the same at your school and you'll appear in next session exams.

Feel free to comment if you have any doubt
Good luck
