Hello Aspirant,
If you have a compartment in Physics again in your 12th, this means that you will need to write the compartment exam and pass it to be eligible to declare as having completed your 12th standard. In terms of Yojana credits (such as Academic Bank of Credits or skill-related schemes), it is usually only applicable after you've successfully completed the subject.
So, for now, it seems that you won't be eligible for any of those credits until you complete your compartment. I don't think you would have to re-study your overall syllabus but you would have to focus on building up on your weaknesses in Physics.
