Hello aspirant,

This all depends on the school that you are studying in, if they don't have attendance eligibility of 75% then you don't need to attend school on regular basis but if not so then you need to go daily. One more option is to apply for an application or talk to your organization that you can't attend daily. Yes, you will like to surely repeat your 12th class for those 2 subjects or you can apply for a re-exam for only those specific exams you need to give again.

Thank you
