if all subjects failed students in 12th can give supplementary exam
Hi Aspirant,
Hope you are doing great as per the question asked by you, if you fail in 1 subject then you can certainly appear in compartment examination but if you fail in 2 subjects then you will be considered as failed and you will not be eligible for admission to undergraduate courses in any university or college this year until you pass the exam.
Hope you found this answer useful. Stay motivated stay positive.
All the best!
