sir maine miss kr diya tha board exams 12th ke because mai icu me thi ab iss year dugi toh kya private certificate ho jayega
greetings,
Yes, if you reappear for the 12th boards the next year you'd have to appear as a private candidate unless you reenroll into the school and repeat the whole year from scratch, please get in touch with your school authorities for more details regarding the processes involved.
good luck
