Hey student,
One has to pass in every individual subject and if one is failed in one subject then he/she has to give the compartment test and if he/she is fails in two or more subject then he/she has to repeat class 12th you can take your best 5 marks but you have to pass in all the subjects.
All the best student,
Hope this helps you.
